This PR adds support for handling action releases — events that
are fired when the user releases all the modifier keys that were part of
an action-triggering shortcut.
If the user holds modifiers and invokes several actions sequentially via
shortcuts (same or different), only the last action is "released" when
its modifier keys released.
~The following methods were added to `Div`:~
- ~`capture_action_release()`~
- ~`on_action_release()`~
- ~`on_boxed_action_release()`~
~They work similarly to `capture_action()`, `on_action()` and
`on_boxed_action()`.~
See the implementation details in [this
comment](https://github.com/zed-industries/zed/pull/8782#issuecomment-2009154646).
Release Notes:
- Added a fast-switch mode to the file finder: hit `p` or `shift-p`
while holding down `cmd` to select a file immediately. (#8258).

Also, add a `deferred` function which takes an element to paint after
the current element tree.
Release Notes:
- Improved the size and position of the hitbox for resizing left, right,
and bottom panels.

### Problem
After transitioning Zed to GPUI 2, we started noticing that interacting
with the mouse on many UI elements would lead to a pretty annoying
flicker. The main issue with the old approach was that hover state was
calculated based on the previous frame. That is, when computing whether
a given element was hovered in the current frame, we would use
information about the same element in the previous frame.
However, inspecting the previous frame tells us very little about what
should be hovered in the current frame, as elements in the current frame
may have changed significantly.
### Solution
This pull request's main contribution is the introduction of a new
`after_layout` phase when redrawing the window. The key idea is that
we'll give every element a chance to register a hitbox (see
`ElementContext::insert_hitbox`) before painting anything. Then, during
the `paint` phase, elements can determine whether they're the topmost
and draw their hover state accordingly.
We are also removing the ability to give an arbitrary z-index to
elements. Instead, we will follow the much simpler painter's algorithm.
That is, an element that gets painted after will be drawn on top of an
element that got painted earlier. Elements can still escape their
current "stacking context" by using the new `ElementContext::defer_draw`
method (see `Overlay` for an example). Elements drawn using this method
will still be logically considered as being children of their original
parent (for keybinding, focus and cache invalidation purposes) but their
layout and paint passes will be deferred until the currently-drawn
element is done.
With these changes we also reworked geometry batching within the
`Scene`. The new approach uses an AABB tree to determine geometry
occlusion, which allows the GPU to render non-overlapping geometry in
parallel.
### Performance
Performance is slightly better than on `main` even though this new
approach is more correct and we're maintaining an extra data structure
(the AABB tree).
Release Notes:
- Fixed a bug that was causing popovers to flicker.

This adds a GPUI fallback for window prompts. Linux does not support
this feature by default, so we have to implement it ourselves.
This implementation also makes it possible for GPUI clients to override
the platform prompts with their own implementations.
This is just a first pass. These alerts are not keyboard accessible yet,
does not reflect the prompt level, they're implemented in-window, rather
than as popups, and the whole feature need a pass from a designer.
Regardless, this gets us one step closer to Linux support :)

Release Notes:
- N/A
This uses bounds checking alone to determine hover state to avoid
flicker. It's a short-term solution because the rendering is incorrect.
We think this is better than flickering though and buys us some time as
we work on a more robust solution overall.
Release Notes:
- Fixed flickering when hovering.

Reverts zed-industries/zed#7481
This would regress performance because we'd be using the standard
library's hash maps everywhere, so reverting for now.
This fixes `cmd+k` in the terminal taking 1s to have an effect. It is
now immediate.
It also fixes#7270 by ensuring that we don't set a bad state when
matching keybindings.
It matches keybindings per context and if it finds a match on a lower
context it doesn't keep pending keystrokes. If it finds two matches on
the same context level, requiring more keystrokes, then it waits.
Release Notes:
- Fixed `cmd-k` in terminal taking 1s to have an effect. Also fixed
sporadic non-matching of keybindings if there are overlapping
keybindings.

This PR does some cleanup of the `gpui` docs, making sure we're linking
things appropriately and following good Rust documentation style.
Release Notes:
- N/A
This isn't my favorite idea of a fix, but it does work for now, and it
seems likely the terminal will need to configure other aspects of action
dispatch in the future.
In the future we should explore making it possible to do this via the
keymap, either by making disabling bindings more robust; or by having a
way to indicate immediate mode per binding.
