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.

Fixes: #8050
For some reason that we didn't investigate, if you have view caching
enabled,
and you have non-integer sized bounds, and you are right aligning
things, the
co-ordinates can differ by +/- 1px when using the cached view.
The easiest fix for now is to just not do that.

Part of #7108
This PR includes just the static runnables part. We went with **not**
having a dedicated panel for runnables.
This is just a 1st PR out of N, as we want to start exploring the
dynamic runnables front. Still, all that work is going to happen once
this gets merged.
Release Notes:
- Added initial, static Runnables support to Zed. Such runnables are defined in
`runnables.json` file (accessible via `zed: open runnables` action) and
they can be spawned with `runnables: spawn` action.

This adds the ability to navigate to/from docks (Terminal, Project,
Collaboration, Assistant) via keybindings.
When using the `ActivatePaneInDirection` keybinding from the
left/bottom/right dock, we check whether the movement is towards the
center panel. If it is, we focus the last active pane.
Fixes https://github.com/zed-industries/zed/issues/6833 and it came up
in a few other tickes/discussions.
Release Notes:
- Added ability to navigate to docks and back to the editor using the
`workspace::ActivatePaneInDirection` action (by default bound to `Ctrl-w
[hjkl]` in Vim mode).
([#6833](https://github.com/zed-industries/zed/issues/6833)).
## Drawback
There's this weird behavior: if you start Zed and no files are opened,
you focus terminal, go left (project panel), then back to right to
terminal, the terminal isn't focused. Even though we focus it in the
code.
Maybe this is a bug in the current focus handling code?

In the old world, panel loading happened strictly before workspace
deserialization. Now it's inverted.
Fix this by storing on the dock the serialized state so they can restore
state as panels are loaded.
This PR renames the `h_stack` and `v_stack` to `h_flex` and `v_flex`,
respectively.
We were previously using `h_stack` and `v_stack` to match SwiftUI, but
`h_flex` and `v_flex` fit better with the web/flexbox terminology that
the rest of GPUI uses.
Additionally, we were already calling the utility functions used to
implement `h_stack` and `v_stack` by the new names.
Release Notes:
- N/A
This PR renames the `IconElement` component to just `Icon`.
This better matches the rest of our components, as `IconElement` was the
only one using this naming convention.
The `Icon` enum has been renamed to `IconName` to free up the name.
I was trying to come up with a way that would allow rendering an
`Icon::Zed` directly (and thus make the `IconElement` a hidden part of
the API), but I couldn't come up with a way to do this cleanly.
Release Notes:
- N/A
Since we don't want tabs, I think it would be better to render the toolbar
for ourselves directly and handle switching between conversations.
