Cherry-picked Revert "Changed cmd+w with no open tabs to close window
(#10740)" (#10986)

This PR reverts #10740, as it makes it too easy to close Zed
accidentally.

Quitting Zed when you don't mean to is disruptive and can break your
flow. This is even more the case when you're collaborating.

Therefore, we shouldn't make it easy to quit Zed when you don't mean to.

If we want to bring back this behavior it needs to have a corresponding
setting that should, in my opinion, be **off** by default. Additionally,
someone made the good point that this behavior should not be present on
Linux or Windows.

This reverts commit 5102e37a5bc344cb1f5f2a4116b55d4d3afafbb0.

Release Notes:

- Changed `cmd-w` with no open tabs to no longer close the window
(preview-only).

Cherry-picked Restore the previous styles for single-line editors
(#10951)

This PR fixes a bug introduced in #10870 that caused editors used as
single-line inputs to have the wrong text style.

If this change was intentional for something relating to the new
Assistant panel, we'll need to figure out a way to change it without
breaking these other usages.

This PR fixes the way we select the primary language server for use with
formatting.

Previously we were just taking the first one in the list, but this could
be the wrong one in cases where a language server was provided by an
extension in conjunction with a built-in language server (e.g.,
Tailwind).

We now use the `primary_language_server_for_buffer` method to more
accurately identify the primary one.

Fixes https://github.com/zed-industries/zed/issues/10902.

Release Notes:

- Fixed an issue where the wrong language server could be used for
formatting.

This PR syncs the `Cargo.toml` version with the `extension.toml`
version.

We should try to keep these in sync.

This PR extracts Deno support into an extension and removes the built-in
Deno support from Zed.

When using the Deno extension, you'll want to add the following to your
settings to disable the built-in TypeScript and ESLint language servers
so that they don't conflict with Deno's functionality:

```json
{
  "languages": {
    "TypeScript": {
      "language_servers": ["deno", "!typescript-language-server", "!eslint", "..."]
    },
    "TSX": {
      "language_servers": ["deno", "!typescript-language-server", "!eslint", "..."]
    }
  }
}

```

Release Notes:

- Removed built-in support for Deno, in favor of making it available as
an extension.

This PR adds a new `language_servers` setting underneath the language
settings.


This setting controls which of the available language servers for a
given language will run.

The `language_servers` setting is an array of strings. Each item in the
array must be either:

- A language server ID (e.g., `"rust-analyzer"`,
`"typescript-language-server"`, `"eslint"`, etc.) denoting a language
server that should be enabled.
- A language server ID prefixed with a `!` (e.g., `"!rust-analyzer"`,
`"!typescript-language-server"`, `"!eslint"`, etc.) denoting a language
server that should be disabled.
- A `"..."` placeholder, which will be replaced by the remaining
available language servers that haven't already been mentioned in the
array.

For example, to enable the Biome language server in place of the default
TypeScript language server, you would add the following to your
settings:

```json
{
  "languages": {
    "TypeScript": {
      "language_servers": ["biome", "!typescript-language-server", "..."]
    }
  }
}
```

More details can be found in #10906.

Release Notes:

- Added `language_servers` setting to language settings for customizing
which language server(s) run for a given language.

This is a crate only addition of a new version of the AssistantPanel.
We'll be putting this behind a feature flag while we iron out the new
experience.

- N/A

I saved the `file_types.json` file and got a diff because it had some
trailing whitespace. I ran
[`lineman`](https://github.com/JosephTLyons/lineman) on the codebase.
I've done this before, but this time, I've added in the following
settings to our `.zed` local settings, to make sure every future save
respects our desire to have consistent whitespace formatting.

```json
"remove_trailing_whitespace_on_save": true,
"ensure_final_newline_on_save": true
```

I'm not a huge fan of this change (& I expect the placement to change).
The plan is to have the button in a toolbar of terminal panel, but I'm
not sure if occupying a whole line of vertical space for a single button
is worth it; I suppose we might want to put more of tasks ui inside of
that toolbar.
Release Notes:

- Removed task status indicator and added "Spawn task" action to
terminal panel context menu.

This pull request introduces the new
`ElementContext::request_autoscroll(bounds)` and
`ElementContext::take_autoscroll()` methods in GPUI. These new APIs
enable container elements such as `List` to change their scroll position
if one of their children requested an autoscroll. We plan to use this in
the revamped assistant.

As a drive-by, we also:

- Renamed `Element::before_layout` to `Element::request_layout`
- Renamed `Element::after_layout` to `Element::prepaint`
- Introduced a new `List::splice_focusable` method to splice focusable
elements into the list, which enables rendering offscreen elements that
are focused.
