Adds the initial semblance of a keymap UI. It is currently gated behind the `settings-ui` feature flag. Follow up PRs will add polish and missing features.

Closes #ISSUE
Adds a very simple API to track metadata about keybindings in GPUI,
namely the source of the binding. The motivation for this is displaying
the source of keybindings in the [keymap
UI](https://github.com/zed-industries/zed/pull/32436).
The API is designed to be as simple and flexible as possible, storing
only a `Option<u32>` on the bindings themselves to keep the struct
small. It is intended to be used as an index or key into a table/map
created and managed by the consumer of the API to map from indices to
arbitrary meta-data. I.e. the consumer is responsible for both
generating these indices and giving them meaning.
The current usage in Zed is stateless, just a mapping between constants
and User, Default, Base, and Vim keymap sources, however, this can be
extended in the future to also track _which_ base keymap is being used.
Release Notes:
- N/A *or* Added/Fixed/Improved ...
* Collects and reports all parse errors
* Shares parsed `KeyBindingContextPredicate` among the actions.
* Updates gpui keybinding and action parsing to return structured
errors.
* Renames "block" to "section" to match the docs, as types like
`KeymapSection` are shown in `json-language-server` hovers.
* Removes wrapping of `context` and `use_key_equivalents` fields so that
`json-language-server` auto-inserts `""` and `false` instead of `null`.
* Updates `add_to_cx` to take `&self`, so that the user keymap doesn't
get unnecessarily cloned.
In retrospect I wish I'd just switched to using TreeSitter to do the
parsing and provide proper diagnostics. This is tracked in #23333
Release Notes:
- Improved handling of errors within the user keymap file. Parse errors
within context, keystrokes, or actions no longer prevent loading the key
bindings that do parse.
Closes #16343Closes#10972
Release Notes:
- (breaking change) On macOS when using a keyboard that supports an
extended Latin character set (e.g. French, German, ...) keyboard
shortcuts are automatically updated so that they can be typed without
`option`. This fixes several long-standing problems where some keyboards
could not type some shortcuts.
- This mapping works the same way as
[macOS](https://developer.apple.com/documentation/swiftui/view/keyboardshortcut(_:modifiers:localization:)).
For example on a German keyboard shortcuts like `cmd->` become `cmd-:`,
`cmd-[` and `cmd-]` become `cmd-ö` and `cmd-ä`. This mapping happens at
the time keyboard layout files are read so the keybindings are visible
in the command palette. To opt out of this behavior for your custom
keyboard shortcuts, set `"use_layout_keys": true` in your binding
section. For the mappings used for each layout [see
here](https://github.com/zed-industries/zed/blob/a890df1863ca939ee7f0ada6e629b6f83eb18bc5/crates/settings/src/key_equivalents.rs#L7).

Simplify key dispatch code.
Previously we would maintain a cache of key matchers for each context
that
would store the pending input. For the last while we've also stored the
typed prefix on the window. This is redundant, we only need one copy, so
now
it's just stored on the window, which lets us avoid the boilerplate of
keeping
all the matchers in sync.
This stops us from losing multikey bindings when the context on a node
changes
(#11009) (though we still interrupt multikey bindings if the focus
changes).
While in the code, I fixed up a few other things with multi-key bindings
that
were causing problems:
Previously we assumed that all multi-key bindings took precedence over
any
single-key binding, now this is done such that if a user binds a
single-key
binding, it will take precedence over all system-defined multi-key
bindings
(irrespective of the depth in the context tree). This was a common cause
of
confusion for new users trying to bind to `cmd-k` or `ctrl-w` in vim
mode
(#13543).
Previously after a pending multi-key keystroke failed to match, we would
drop
the prefix if it was an input event. Now we correctly replay it
(#14725).
Release Notes:
- Fixed multi-key shortcuts not working across completion menu changes
([#11009](https://github.com/zed-industries/zed/issues/11009))
- Fixed multi-key shortcuts discarding earlier input
([#14445](https://github.com/zed-industries/zed/pull/14445))
- vim: Fixed `jk` binding preventing you from repeating `j`
([#14725](https://github.com/zed-industries/zed/issues/14725))
- vim: Fixed `escape` in normal mode to also clear the selected
register.
- Fixed key maps so user-defined mappings take precedence over builtin
multi-key mappings
([#13543](https://github.com/zed-industries/zed/issues/13543))
- Fixed a bug where overridden shortcuts would still show in the Command
Palette
