This PR makes it so both Assistant panels are visible when in the
`assistant2` feature flag.

This way folks can continue using Assistant1 if Assistant2 isn't meeting
their needs.

Right now they are shown as two different panels shown in the status bar
(although using the same icon), but this is just a temporary state until
we can surface the Assistant1 functionality in Assistant2 somehow.

Note that the inline assist will always use the Assistant2 panel.

Release Notes:

- N/A

Most notably, trying out a different icon and adding the "Completion"
word to the side of the provider name.

![editor_scrollbars](https://github.com/user-attachments/assets/76c26776-8fe4-47f8-9c79-9add7d7d2151)

Closes #4427 

Release Notes:

- Added a horizontal scrollbar to the editor panel
- Added `axis` option to `scrollbar` in the Zed configuration, which can
forcefully disable either the horizontal or vertical scrollbar
- Added `horizontal_scroll_margin` equivalent to
`vertical_scroll_margin` in the Zed configuration

Rough Edges:

This feature seems mostly stable from my testing. I've been using a
development build for about a week with no issues. Any feedback would be
appreciated. There are a few things to note as well:

1. Scrolling to the lower right occasionally causes scrollbar clipping
on my end, but it isn't consistent and it isn't major. Some more testing
would definitely be a good idea. [FIXED]
2. Documentation may need to be modified
3. I added an `AxisPair` type to the `editor` crate to manage values
that have a horizontal and vertical variant. I'm not sure if that's the
optimal way to do it, but I didn't see a good alternative. The `Point`
type would technically work, but it may cause confusion.

This makes inline completions show up in the completion menu even if the
user has set `"show_completion_documentation": false` in their settings,
because there is no other way to show the Zeta completion.

Release Notes:
- Changed inline completions to show up inside the normal completions in
case LSP and inline-completions are available. In that case, the inline
completion will be the first entry in the menu and can be selected with
`<tab>`.

This reverts commit 38c0aa303e8c58238bceea9ee719ef2716158e81 from
#22075.

Release Notes:

- N/A

* Makes `dilate` and `inset` return.

* Implements `Add<Point<T>>` and `Sub<Point<T>>`.

* Makes some trait constraints more precise.

* Now decides whether the menu is above or below the target position
before rendering it. This causes its position to no longer vary
depending on the length of completions

* When the text area is height constrained (< 12) lines, now chooses the
side which has the most space. Before it would always display above if
height constrained below.

* Misc code cleanups

Release Notes:

- Improved completions menu layout to be more stable and use available
space better.

This PR makes it so `assistant` and `assistant2` both use the same
action for inline assist (`zed_actions::InlineAssist`).

This makes it so the keybindings to deploy the inline assist seamlessly
swap based on the feature flag without needing to rebind them.

One minor caveat: if you're using `assistant2` the action name in the
command palette will be `assistant: inline assist`.

Release Notes:

This PR adds an action and associated keybinding

* Reuse center terminals for tasks, when requested
* Extend task templates with `RevealTarget`, moving it from
`TaskSpawnTarget` into the core library
* Use `reveal_target` instead of `target` to avoid misinterpretations in
the task template context
* Do not expose `SpawnInTerminal` to user interface, avoid it
implementing `Serialize` and `Deserialize`
* Remove `NewCenterTask` action, extending `task::Spawn` interface
instead
* Do not require any extra unrelated parameters during task resolution,
instead, use task overrides on the resolved tasks on the modal side
* Add keybindings for opening the task modal in the
`RevealTarget::Center` mode
