This PR cleans up some color & elevation misc.
### Don't allow deriving Color from Hsla
The point of the [ui::Color] enum is to encourage consistent color
usage, and the the Color::Custom case is really only meant for cases
where we have no other choice.
`impl From<Hsla> for Color` encourages blindly passing colors into
`Color::Custom` – with this in place we might as well remove the entire
`Color` enum.
The usages that were updated due to this removal were for colors that
already exist in the Color enum, making it even more clear that it
didn't make sense to have this.
### `ElevationIndex` -> `Elevation`
This name would make more sense if we had an `Elevation` in the first
place. The new name is more clear.
#### `Button::elevation`
As part of this change I also updated button's `layer` method to
`elevation`, since it takes an elevation. This method still has the
following issue:
You want to use `Button::elevation` when it's default colors are
invisible on the layer you are rendering the button on. However, current
this method uses the elevation's `bg` color, rather than it's
`on_elevation_bg`.
Ideally when you use `Button::elevation` you want to pass the elevation
you are _on_, not choosing one that will show up the elevation you are
on.
This change will be in a separate PR, as it likely will have widespread
visual impact across the app.

This PR adds the first part of our planned extended notification system:
StatusToasts.
It also makes various updates to ComponentPreview and adds a `Styled`
extension in `ui::style::animation` to make it easier to animate styled
elements.
_**Note**: We will be very, very selective with what elements are
allowed to be animated in Zed. Assume PRs adding animation to elements
will all need to be manually signed off on by a designer._
## Status Toast

These are designed to be used for notifying about things that don't
require an action to be taken or don't need to be triaged. They are
designed to be ignorable, and dismiss themselves automatically after a
set time.
They can optionally include a single action.
Example: When the user enables Vim Mode, that action might let them undo
enabling it.

Status Toasts should _not_ be used when an action is required, or for
any binary choice.
If the user must provide some input, this isn't the right component!
### Out of scope
- Toasts should fade over a short time (like AnimationDuration::Fast or
Instant) when dismissed
- We should visually show when the toast will dismiss. We'll need to
pipe the `duration_remaining` from the toast layer -> ActiveToast to do
this.
- Dismiss any active toast if another notification kind is created, like
a Notification or Alert.

This PR updates the ui of the git panel. It removes the header from the
panel and unifies the repository, branch and commit controls in the
bottom section.
It also adds a secondary menu to the primary button giving access to a
variety of actions for managing local and remote changes:

Known issues (will be fixed in a later pr)
- Spinner showing git operation progress was removed, will be re-added
- Clicking expand with the panel editor focused will commit (due to
shared action name. Already tracked)
Before | After

(Also adds `component`, `linkme` to cargo-machete ignore as they are
used in the `IntoComponent` proc-macro and will always be incorrectly
flagged as unused)

There's still a bit more work to do on this, but this PR is compiling
(with warnings) after eliminating the key types. When the tasks below
are complete, this will be the new narrative for GPUI:
- `Entity<T>` - This replaces `View<T>`/`Model<T>`. It represents a unit
of state, and if `T` implements `Render`, then `Entity<T>` implements
`Element`.
- `&mut App` This replaces `AppContext` and represents the app.
- `&mut Context<T>` This replaces `ModelContext` and derefs to `App`. It
is provided by the framework when updating an entity.
- `&mut Window` Broken out of `&mut WindowContext` which no longer
exists. Every method that once took `&mut WindowContext` now takes `&mut
Window, &mut App` and every method that took `&mut ViewContext<T>` now
takes `&mut Window, &mut Context<T>`
Not pictured here are the two other failed attempts. It's been quite a
month!
Tasks:
- [x] Remove `View`, `ViewContext`, `WindowContext` and thread through
`Window`
- [x] [@cole-miller @mikayla-maki] Redraw window when entities change
- [x] [@cole-miller @mikayla-maki] Get examples and Zed running
- [x] [@cole-miller @mikayla-maki] Fix Zed rendering
- [x] [@mikayla-maki] Fix todo! macros and comments
- [x] Fix a bug where the editor would not be redrawn because of view
caching
- [x] remove publicness window.notify() and replace with
`AppContext::notify`
- [x] remove `observe_new_window_models`, replace with
`observe_new_models` with an optional window
- [x] Fix a bug where the project panel would not be redrawn because of
the wrong refresh() call being used
- [x] Fix the tests
- [x] Fix warnings by eliminating `Window` params or using `_`
- [x] Fix conflicts
- [x] Simplify generic code where possible
- [x] Rename types
- [ ] Update docs
### issues post merge
- [x] Issues switching between normal and insert mode
- [x] Assistant re-rendering failure
- [x] Vim test failures
- [x] Mac build issue

- Adds the Switch component
- Updates `Selected`, `Selectable` -> `ToggleState`, `Toggleable`
- Adds `checkbox` and `switch` functions to align better with other
elements in our layout system.
We decided not to merge Switch and Checkbox. However, in a followup I'll
introduce a Toggle or AnyToggle enum so we can update
`CheckboxWithLabel` -> `ToggleWithLabel` as this component will work
exactly the same with either a Checkbox or a Switch.

Similar to https://github.com/zed-industries/zed/pull/18690 &
https://github.com/zed-industries/zed/pull/18695, this PR enables
required docs for `ui` and does some cleanup.
Changes:
- Enables the `deny(missing_docs)` crate-wide.
- Adds `allow(missing_docs)` on many modules until folks pick them up to
document them
- Documents some modules (all in `ui/src/styles`)
- Crate root-level organization: Traits move to `traits`, other misc
organization
- Cleaned out a bunch of unused code.
Note: I'd like to remove `utils/format_distance` but the assistant panel
uses it. To move it over to use the `time_format` crate we may need to
update it to use `time` instead of `chrono`. Needs more investigation.
Release Notes:
