This PR changes the approach we're using to render the channel buttons
to use a more straightforward (and less hacky) approach.
### Motivation
Even with the variety of hacks that were employed to make the current
approach work, there are still a number of issues with the current
solution:
- Hovering in the empty space to the left of a channel doesn't correctly
apply the hover background to the container for the channel buttons
- Hovering to the very right of the collab panel (right on top of the
drag handle) causes the channel button container to apply its hover
background without applying it to the rest of the row
- The buttons would still get pushed off to the right by the indent
space in the channel tree, resulting in jagged indicators at small sizes
Additionally, the rectangular background placed behind the channel
buttons still didn't look great when it overlapped with the channel
names.
### Explanation
For these reasons, I decided to explore a simpler approach that
addresses these issues, albeit with some tradeoffs that I think are
acceptable.
We now render the absolutely-positioned button container as a sibling
element of the `ListItem`. This is to avoid issues with the container
getting pushed around based on the contents of the `ListItem` rather
than staying absolutely positioned at the end of the row.
We also have gotten rid of the background for the button container, and
now rely on the background of the individual `IconButton`s to occlude
the channel name behind them when the two are overlapping.
Here are some examples of the new UI in various configurations:

### Tradeoffs
The new approach comes with the following tradeoffs that I am currently
aware of:
The occlusion can look a little weird when the icons are in the middle
of a channel name (as opposed to fully occluding the end of the channel
name):

Hovering one of the icons causes the icon to be hovered instead of the
row:

Release Notes:
- Improved the way channel buttons are displayed.
We had introduced these mutexes at a time when `gpui2` required app
entities to be `Sync`, but they are no longer needed. Removing them now
because we're trying to find out why we're sometimes getting crashes and
deadlocks in livekit, and we didn't before.
This PR cleans up a number of references in doc comments in the `ui` and
`theme` crates so that `rustdoc` will link and display them correctly.
Release Notes:
- N/A
This PR removes the `Default` impl for `StatusColors`.
Since we need default light and dark variants for `StatusColors`, we
can't use a single `Default` impl.
Release Notes:
- N/A
This PR renames the `IconElement` component to just `Icon`.
This better matches the rest of our components, as `IconElement` was the
only one using this naming convention.
The `Icon` enum has been renamed to `IconName` to free up the name.
I was trying to come up with a way that would allow rendering an
`Icon::Zed` directly (and thus make the `IconElement` a hidden part of
the API), but I couldn't come up with a way to do this cleanly.
Release Notes:
- N/A
This PR adds some basic stories for collab notifications to make them
easier to work on:

I factored out a `CollabNotification` component that defines the general
structure for one of these notifications, and this is the component that
we use in the stories, with representative values passed to it to
simulate the different instances of the notification.
We can't use the actual notification components in the stories due to
their data dependencies.
Release Notes:
- N/A
This PR fixes an issue where right-click on any project panel entry
would cause the context menu on the root of the project panel
(introduced in #3954) to deploy.
We need to stop propagation in the handler on the inner project panel
list items so that the click event doesn't bubble up the tree.
Release Notes:
- Fixed an issue where the project panel was always deploying the root
context menu rather than on the clicked item.
