This PR restores the `Global` trait's status as a marker trait.

This was the original intent from #7095, when it was added, that had
been lost in #9777.

The purpose of the `Global` trait is to statically convey what types can
and can't be accessed as `Global` state, as well as provide a way of
restricting access to said globals.

For example, in the case of the `ThemeRegistry` we have a private
`GlobalThemeRegistry` that is marked as `Global`:
https://github.com/zed-industries/zed/blob/91b3c24ed35d58438ae33970f07d1ff01d3acfc7/crates/theme/src/registry.rs#L25-L34

We're then able to permit reading the `ThemeRegistry` from the
`GlobalThemeRegistry` via a custom getter, while still restricting which
callers are able to mutate the global:
https://github.com/zed-industries/zed/blob/91b3c24ed35d58438ae33970f07d1ff01d3acfc7/crates/theme/src/registry.rs#L46-L61

This PR adds support for replacing the current preview tab when using
GoToDefinition. Previously a tab, that was navigated away from, was
converted into a permanent tab and the new tab was opened as preview.

Without `enable_preview_from_code_navigation`:


https://github.com/zed-industries/zed/assets/53836821/99840724-d6ff-4738-a9c4-ee71a0001634

https://github.com/zed-industries/zed/assets/53836821/8c60efcb-d597-40bf-b08b-13faf5a289b6

Note: In the future I would like to improve support for the navigation
history, because right now tabs that are not "normal" project items,
e.g. FindAllReferences cannot be reopened

Release Notes:

- Added support for replacing the current preview tab when using code
navigation (`enable_preview_from_code_navigation`)

This PR adds the ability for the ESLint language server (`eslint`) to be
controlled by the `language_servers` setting.

Now in your settings you can indicate that the ESLint language server
should be used for a given language, even if that language does not have
the ESLint language server registered for it already:

```json
{
  "languages": {
    "My Language": {
      "language_servers": ["eslint", "..."]
    }
  }
}
```

Release Notes:

- N/A

This should have fixed the problems that some users were reporting with
https://github.com/zed-industries/zed/pull/10695 .

The problem was with devices which send more than one valuator axis in a
single event whereas the original PR assumed there would only ever be
one axis per event. This version also does away with the complicated
device selection and instead just uses the master pointer device, which
automatically uses all sub-pointers.

Edit: Confirmed working for one of the user's which the first attempt
was broken for.

Release Notes:

- Added smooth scrolling for X11 on Linux
- Added horizontal scrolling for X11 on Linux

By setting the app id, window managers like `sway` can apply custom
configuration like `for_window [app_id="zed"] floating enable`.
Tested using `wlprop`/`hyprctl activewindow` for wayland, `xprop` for
x11.


Release Notes:

- Zed now sets the window app id / class, which can be used e.g. in
window managers like `sway`/`i3` to define custom rules

Release Notes:

- Fixes diagnostic panic better (follow up from #11066)

Addresses #10812 

Release Notes:

- Launching an empty already-running Zed application now behaves like a
regular startup and respects the user `resume_on_startup` setting.
([#10812](https://github.com/zed-industries/zed/issues/10812)).

See attached showcase which highlights how the previous project can now
be re-opened through both "quit" and "close window".

This has a noticeable performance benefit on startup/project resume
time.

This should also make the behaviour of closing/opening an application
consistent between macOS/Linux/Windows.

The culprit behind ghost images in transparent windows and bad
performance with blurred windows turns out to be one and the same:
window shadows. The simplest and most popular fix appears to be to
simply disable shadows on non-opaque windows so let's just do that.

Disabling shadows on a window that is already visible however leaves the
shadow on screen, detached from the window, until a full screen effect
such as exposé or a virtual desktop switch wipes it clean. There does
not seem to be any known solution to this, and it does not affect
windows created after switching to a transparent theme so this is a good
enough compromise for now.



Release Notes:

- Fixed ghostly artifacts in transparent window backgrounds.
- Fixed sluggishness with blurred window backgrounds.

This is a follow-up to #10685 which started to hide these errors instead
of displaying them to the user.

But the errors are still noisy and not actionable, so we hide them
instead.

Release Notes:

- Removed error message being logged when `git blame` is run in a
repository without commits.

`rulesCustomizations` is an array of rule severity overrides. Globs can
be used to apply default severities for multiple rules. See
[docs](https://github.com/microsoft/vscode-eslint/blob/553e632fb4cf073fce1549fb6c3c1b5140a52ebb/README.md?plain=1#L312-L333)

            "settings": {
                "rulesCustomizations": [

                    { "rule": "*", "severity": "warn" }
                ]
            }
        }
    }
}

Fix missed delete in project panel
Fix blinking scrollbar from selections-in-scrollbar change

Release Notes:

- N/A (nightly only)

We're planning to associate "selection sources" with global element ids
to allow arbitrary UI text to be selected in GPUI. Previously, global
ids were not exposed outside the framework and we entangled management
of the element id stack with element state access. This was more
acceptable when element state was the only place we used global element
ids, but now that we're planning to use them more places, it makes sense
to deal with element identity as a first-class part of the element
system. We now ensure that the stack of element ids which forms the
current global element id is correctly managed in every phase of element
layout and paint and make the global id available to each element
method. In a subsequent PR, we'll use the global element id as part of
implementing arbitrary selection for UI text.

fixes https://github.com/zed-industries/zed/issues/7228
fixes https://github.com/zed-industries/zed/issues/5094

Release Notes:

- Added a new `project_panel::Trash` action and changed the default
behavior for `backspace` and `delete` in the project panel to send a
file to the systems trash, instead of permanently deleting it
([#7228](https://github.com/zed-industries/zed/issues/7228),
[#5094](https://github.com/zed-industries/zed/issues/5094)). The
original behavior can be restored by adding the following section to
your keybindings:

```json5
[
// ...Other keybindings...
  {
    "context": "ProjectPanel",
    "bindings": {
        "backspace": "project_panel::Delete",
        "delete": "project_panel::Delete",
    }
  }
]

Release Notes:

- vim: Support `-` to go to `parent directory` of the project panel.

As mentioned in the comments of #11073 this adds support for netrw's `-`
to go to the parent directory in the project panel. Again tested on
linux only.

This PR adds cursor markers to the scrollbar. They work similar to
VSCode:

1. A cursor marker takes the whole scrollbar width.
2. It's always 2px high.
3. It uses the player's `cursor` color, so it may be helpful in the
collaboration mode.

There's a setting to switch cursor markers on/off:

```json
{
  "scrollbar": {
    "cursors": true
  }
}
```

Implementation details:

- Unlike other markers, cursor markers are displayed synchronously.
Otherwise they don't feel smooth and sometimes freez on prolonged
up/down navigation.
- Cursor markers are automatically switched off when it's more than 100
of them.
- The minimum (non-cursor) marker height is now 5px. It allows the user
to see other markers under the cursor marker.
- The way the minimum height is imposed on markers has changed a bit to
keep consistency between markers of different types.
- Selected symbol markers use less vibrant color (`info` faded out a
little).

Release Notes:

- Added displaying of cursor markers in the scrollbar. They can be
switched on/off by the `scrollbar.cursors` setting.

Make it more likely the draft release notes work...

Release Notes:
- vim: Support `g g`/`G` to go to top/bottom of the project panel.

In vim type environments i usually expect to be able to jump to the top
and bottom and i was confused as to why that wasn't possible in the
project panel. So i added it. If anyone using different keymaps also
thinks this might be useful i would be happy to add other defaults. I
think for vim mode it is the most useful though, because you tend to not
use your mouse in vim mode.

This is my first contribution to any rust project, but it seemed like a
good starting point.
The function select_last() is inspired by select_first.
I was also thinking about adding a bigger jump keybinding, that would
jump for example 5 entries up / down, with vim default keybindings "{" /
"}".
FYI: I tested this on linux only and don't have access to any macos
machines.

fixes #11048

## Problem
in the situation `press right`, `press left`, `release right` the
following happens right now:

- `keypressed right`, `current_keysym` is set to `right`
- `keypressed left`, `current_keysym` is set to `left`

the repeat timer runs asynchronously and emits keyrepeats since
`current_keysym.is_some()`

- `keyreleased right`, `current_keysym` is set to None

the repeat timer no longer emits keyrepeats

- `keyreleased left`, this is where `current_keysym` should actually be
set to None.

## Solution
Only reset `current_keysym` if the released key matches the last pressed
key.

* Otherwise is_maximized always returns `true`



Release Notes:

- Fixed maximized state. Tested with a dummy maximize/restore button
with the `zoom()` (not implemented yet). Without the right `maximized`,
in toggle zoom function is not possible to call `set_maximized()` or
`unset_maximized()`.

```rust
    fn zoom(&self) {
      if self.is_maximized() {
        self.borrow_mut().toplevel.unset_maximized();
      } else {
        self.borrow_mut().toplevel.set_maximized();
      }
    }
```

Release Notes:

- Added support for all `OpenType` font features to DirectWrite.

Release Notes:

- Fixed a panic in populating diagnostics

Fixes a panic related to rendering checkboxes, see #10824.

Currently we are rendering a list into a single block, meaning the whole
block has to be rendered when it is visible on screen. This would lead
to performance problems when a single list block contained a lot of
items (especially if it contained checkboxes). This PR splits up list
items into separate blocks, meaning only the actual visible list items
on screen get rendered, instead of the whole list.
A nice side effect of the refactoring is, that you can actually click on
individual list items now:
