Completes #7228.
Adds back Backspace as the main delete key binding and makes Linux
bindings consistent with macOS
Release Notes:
- ⌘-Delete/⌘-Backspace will now suppress deletion confirmation prompts
in project panel
([#7228](https://github.com/zed-industries/zed/issues/7228)).
This PR changes GPUI to open windows with a default size and location,
and to otherwise inherit from their spawning window.
Note: The linux build now crashes on startup.

### 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.

Release Notes:
- Added `workspace::SendKeystrokes` to enable mapping from one key to a
sequence of others
([#7033](https://github.com/zed-industries/zed/issues/7033)).
Improves #7033. Big thank you to @ConradIrwin who did most of the heavy
lifting on this one.
This PR allows the user to send multiple keystrokes via custom
keybinding. For example, the following keybinding would go down four
lines and then right four characters.
```json
[
{
"context": "Editor && VimControl && !VimWaiting && !menu",
"bindings": {
"g z": [
"workspace::SendKeystrokes",
"j j j j l l l l"
],
}
}
]
```

This should prevent a class of bugs where one queries the wrong type of
global, which results in oddities at runtime.

This PR does some cleanup of the `gpui` docs, making sure we're linking
things appropriately and following good Rust documentation style.

I was unable to run the collab tests locally because I would run out of
file descriptors.
From some digging it turned out that tokio allocates a new file
descriptor to do work on the CurrentThread using KQUEUE.
We create a new tokio Runtime with each database connection, and these
database connections were being retained by the Client, which is
retained by the Context.
Cleaning up our leaked contexts (and an unrelated retain cycle in the
UserStore) fixes the problem (though does make me
wonder if a different approach might be preferrable).

This PR updates the tenses used by the summary line of doc comments to
match the [Rust API documentation
conventions](https://rust-lang.github.io/rfcs/1574-more-api-documentation-conventions.html#summary-sentence).
Specifically:
> The summary line should be written in third person singular present
indicative form. Basically, this means write ‘Returns’ instead of
‘Return’.
I'm sure there are plenty occurrences that I missed.

Also:
- Rename cx.on_blur to cx.on_focus_lost
- Fix a bug where notify calls in focus handlers were ignored
- Fix a bug where vim would get stuck in the wrong mode when switching
windows
Release Notes:
- (preview only) vim: fix switching between multiple windows
This commit mostly fixes invalid URLs in docstrings. It also
encapsulates crates we reexport (serde stuff + linkme) into a public
module named "private" in order to reduce the API surfaced through docs.
Moreover, I fixed up a bunch of crates that were pulling serde_json in
through gpui explicitly instead of using Cargo manifest.
