This PR fixes two bugs we discovered in Zed's mouse event handling while
investigating an interesting and mysterious bug we we were seeing, where
spurious `MouseMoved` events would continuously be dispatched after
control-clicking.
Release Notes:
- Fixed a rendering glitch that could occur after control-clicking
certain elements.
I want to use this on another branch, but it's a sweeping change,
so this prepares the ground for it. This can always be reverted if
it doesn't work out.

I've found a crate that handles both comments and trailing commas in
JSON. It is a fork of `serde_json`, but it is maintained & up-to-date.
Sadly RawValue seems to not play nicely with it; I've ran into
deserialisation issues around use of RawValue. For this PR I've migrated
to `Value` API.
Obviously this is just a point of discussion, not something I'd merge
straight away. There may be better solutions to this particular problem.
I've also noticed that `serde_json_lenient` does not handle trailing
commas after bindings array. I'm not sure how big of an issue that is.
Release Notes:
- Improved handling of trailing commas in settings files.
[#1322](https://github.com/zed-industries/community/issues/1322)
During `layout`, we now pass a mutable reference to the element's
parent view. This is a recursive process that causes the view to
be removed from `AppContext` and then re-inserted back into it once
the layout is complete.
As such, querying parent views during `layout` does not work as such
views will have been removed from `AppContext` and not yet re-inserted
into it. This caused a bug in `KeystrokeLabel`, which used the `keystrokes_for_action`
method to query its ancestors to determine their type id and keymap context.
Now, any time a view notifies, we will cache its keymap context so that
we don't need to query the parent view during `layout`.
This is achieved by moving `available_actions` into `AsyncAppContext` (where
we know no view/window is on the stack) and `keystrokes_for_action` into `LayoutContext`
where we'll fetch the previous frame's ancestors and notify the current view if those
change after we perform a layout.
