This PR adds a new development credentials provider for the purpose of
streamlining local development against production collab.

## Problem

Today if you want to run a development build of Zed against the
production collab server, you need to either:

1. Enter your keychain password every time in order to retrieve your
saved credentials
2. Re-authenticate with zed.dev every time
    - This can get annoying as you need to pop out into a browser window
- I've also seen cases where if you re-auth too many times in a row
GitHub will make you confirm the authentication, as it looks suspicious

## Solution

This PR decouples the concept of the credentials provider from the
keychain, and adds a new development credentials provider to address
this specific case.

Now when running a development build of Zed and the
`ZED_DEVELOPMENT_AUTH` environment variable is set to a non-empty value,
the credentials will be saved to disk instead of the system keychain.

While this is not as secure as storing them in the system keychain,
since it is only used for development the tradeoff seems acceptable for
the resulting improvement in UX.

This aligns the Windows platform implementation with a code style
similar to macOS platform, eliminating most of the `Cell`s and
`Mutex`es. This adjustment facilitates potential future porting to a
multi-threaded implementation if required.

Overall, this PR made the following changes: it segregated all member
variables in `WindowsPlatform` and `WindowsWindow`, grouping together
variables that remain constant throughout the entire app lifecycle,
while placing variables that may change during app runtime into
`RefCell`.

Edit: 
During the code refactoring process, a bug was also fixed.

**Before**: 
Close window when file has changed, nothing happen:

This implements `app_version` on Linux by using an optional,
compile-time `RELEASE_VERSION` env var that can be set.

We settled on the `RELEASE_VERSION` as the name, since it's similar to
`RELEASE_CHANNEL` which we use in Zed.

This PR increases the length of a shortened Git SHA from 6 to 7
characters.

This matches what GitHub uses.

I also took the opportunity to factor out a common method for computing
a short SHA so that we have a single source of truth for the length that
we're using.

Release Notes:

- Increased the short commit SHA length used by git blame from 6 to 7
characters.

Make it easier to edit to select the N/A option.

This fixes a race-condition that showed up when trying to restart
Nightly/Preview/...

When running with these release channels, Zed tries to ensure that
there's only one instance of Zed running.

It does that by listening on a TCP socket to which other instances can
connect on start. If the other instance receives a message, it knows
that another Zed instance is running and exits.

On Linux, though, we ran into a race condition:

1. `kill -0`, which checks whether a process is still running, returns
an error, signalling that the old Zed process has exited
2. BUT: the process was still listening on the TCP port.

It seems like that on Linux, process resources aren't guaranteed to be
cleaned up as soon as signal handling stops working for a process.

The fix is to wait until the process is no longer listening on any TCP
sockets.

There's a slight downside to this: GPUI processes that never listen on
any TCP sockets now have to pay the cost of an additional `lsof` call
when restarting. We do think that it's a reasonable tradeoff for now
though, since the other options (extending the platform interface to
provide callbacks, sharing the listening port in the framework, ...)
seem wider-reaching only to fix a very local bug.

This PR adds a registry for `GitHostingProvider`s.

The intent here is to help decouple these provider-specific concerns
from the lower-level `git` crate.

Similar to languages, the Git hosting providers live in the new
`git_hosting_providers` crate.

This work also lays the foundation for if we wanted to allow defining a
`GitHostingProvider` from within an extension. This could be useful if
we wanted to extend the support to work with self-hosted Git providers
(like GitHub Enterprise).

I also took the opportunity to move some of the provider-specific code
out of the `util` crate, since it had leaked into there.

This PR restructures the way that tools and attachments add information
about the current project to a conversation with the assistant. Rather
than each tool call or attachment generating a new tool or system
message containing information about the project, they can all
collectively mutate a new type called a `ProjectContext`, which stores
all of the project data that should be sent to the assistant. That data
is then formatted in a single place, and passed to the assistant in one
system message.

This prevents multiple tools/attachments from including redundant
context.

This PR fixes a small issue I noticed with resize cursors. The
column/row resize cursors were missing and in a few places we were using
`ew-resize` and `ns-resize` even though the documentation mentions
`col-resize` and `row-resize`.

Finally updated the panes in the workspace to use the new column/row
resize cursors.

Before:

Release Notes:

- Added column/row resize cursor styles to GPUI
- Fixed the existing references that were incorrectly using `ew-resize`
for column resize and `ns-resize` for row resize
- Updated panes to use column/row resize cursors instead on `ew-resize`
and `ns-resize`

Since Windows paths are known to be weird and currently not handled at
all (outside of relative paths that just happen to work), I figured I
would add a windows specific implementation for parsing absolute paths.
It should be functionally the same, of course there's always a chance I
missed an edge case though.

This should fix
- #10849

Note that there are still some cases that will probably break the
current implementation, namely local drives that do not have a drive
letter assigned (not sure how to handle those). There's also UNC paths
but I don't know how important those are at the moment (I'll allow
myself to assume not at all)

This PR replaces all pointer events on X11 with their XI2 equivalents,
which fixes problems with scroll events not being reported when a mouse
button is down. Additionally it closes #11206 by resetting the tracked
global scroll valulator position with `None` on a leave event to prevent
a large scroll delta if scrolling is done outside the window. Lastly, it
resolves the bad window issue kvark was having.

This PR makes the `border` methods require an explicit width instead of
defaulting to 1px.

This breaks convention with Tailwind, but it makes GPUI more consistent
with itself. We already have an edge case where the parameterized method
had to be named `border_width`, since `border` was taken up by an alias
for the 1px variant.

### Before

```rs
div()
    .border()
    .border_t()
    .border_r()
    .border_b()
    .border_l()
    .border_width(px(7.))

### After
