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)

(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)

This PR formalizes design components with the Component and
ComponentPreview traits.
You can open the preview UI with `workspace: open component preview`.
Component previews no longer need to return `Self` allowing for more
complex previews, and previews of components like `ui::Tooltip` that
supplement other components rather than are rendered by default.
`cargo-machete` incorrectly identifies `linkme` as an unused dep on
crates that have components deriving `IntoComponent`, so you may need to
add this to that crate's `Cargo.toml`:
```toml
# cargo-machete doesn't understand that linkme is used in the component macro
[package.metadata.cargo-machete]
ignored = ["linkme"]
```
