Currently we have a single cache for this data shared between all
snapshots which is incorrect, as we might update the cache to a new
version while having old snapshots around which then may try to access
new data with old offsets/rows.

Leverages a new `await_on_background` API that spawns the future on the
background but blocks the current task, allowing to borrow from the
surrounding scope.

Release Notes:
- Fixed new windows underflowing the taskbar on windows
- Improved new windows spawned from maximized or fullscreened windows by
copying the maximized and fullscreened states
We reallocate quite a bunch in this codepath even though we don't need
to, we already roughly know what number of elements we are working with
so we can reduce the required allocations to some degree. This also
reduces the amount of anchor comparisons required.

This basically reduces the main thread work for large enough json (and
other) files from multiple milliseconds (15ms was observed in that test
case) down to microseconds (100ms here).

Windows applications tend to be fairly re-entrant which does not work
well with our current top-level `RefCell` approach. We have worked
around a bunch of panics in the past due to this, but ultimately this
will re-occur (and still does according to sentry) in the future. So
this PR moves all interior mutability down to the fields.

Instead of trying to guess whether we can `--exec`, this now
restructures things to only attempt to use that flag where its
necessary. We only need to `--exec` when we are interested in the shell
output after all.
Release Notes:
- Fixed wsl remoting not working with some nixOS setups
Gist is we only need to block the foreground thread for reparsing if
immediate language changes are useful to the user. That is usually only
the case when they edit the buffer
Release Notes:
- Improved performance of large project searches and project diffs

There is still room for improvement here as `anchor(s)_in_excerpt` is
generally a bad API here due to it reseeking the entire excerpt tree
from the start on every call which we don't really need. But this at
least cuts the seeks down by a factor of 4 for now.
Release Notes:
- Improved performance of bracket colorization in large multibuffers
Introduces new "mapping point cursors" for the different display map
layers allowing one to map multiple points in increasing order more
efficiently than using the one shot operations.
This is used in the `BlockMap::sync` for `header_and_footer_blocks`
which spends a significant time in sumtree traversal due to repeatedly
transforming points between the different layers. This effectively turns
the complexity of those operations from quadratic in the number of
excerpts to linear, as we only go through the respective sumtrees once
instead of restarting from the start over and over again.
Release Notes:
- Improved performance for editors of large multibuffers with many
different files
These are long running foreground tasks that tend to not have pending
await points, meaning once we start executing them they will never
reschedule themselves, starving the foreground thread.
Release Notes:
- Improved git project diff responsiveness
This reduces hangs on windows when we have many tasks queued up on the
main thread that yield a lot.
Release Notes:
- Reduced hangs on windows in some situations

We only clamped the end which for a completely wrong input could cause
us to construct a reversed range which will end up underflowing later
on.

While logically not really correct, its better than tearing down the
application until we figure out the root cause here

It is easy for us to get the two fields out of sync causing weird

While zed itself is not a heavy user of rayon, wasmtime is, especially
for compilation. This change is similar to the rayon default but we
halve the number of threads still so we don't spawn too many threads
overall.
Release Notes:

These appear in a lot of stacktraces (especially on windows) despite
them being plain forwarding calls.
Also removes some intermediate calls within gpui that will only turn
into more unnecessary compiler work.

Before we were simply not rendering anything which could lead to some
very surprising situations when joining channels ...
Now it will look like so

Release Notes:
- Improved rendering of avatars that failed to load by rendering a
fallback icon
Editor is a choke point in our compilation graph while also being a very
common crate that is being edited. So reducing things that depend on it
will generally improve compilation times for us.

This PR introduces a new `MultiBufferOffset` new type wrapping size. The
goal of this is to make it clear at the type level when we are
interacting with offsets of a multi buffer versus offsets of a language
/ text buffer. This improves readability of things quite a bit by making
it clear what kind of offsets one is working with while also reducing
accidental bugs by using the wrong kin of offset for the wrong API.
This PR also uncovered two minor bugs due to that.
Does not yet introduce the MultiBufferPoint equivalent, that is for a
follow up PR.

The powershell we discovered might be in a directory with higher
permission requirements which will cause us to fail using it.
Release Notes:
- Fixed powershell discovery disregarding admin requirements
https://github.com/zed-industries/zed/pull/40883 implemented this
incorrectly. It was marking a random background thread as a wasm thread
(whatever thread picked up the wasm epoch timer background task),
instead of marking the threads that actually run the wasm extension.
This has two implications:
1. it didn't prevent extension panics from tearing down as planned
2. Worse, it actually made us hide legit panics in sentry for one of our
background workers.
Now 2 still technically applies for all tokio threads after this, but we
basically only use these for wasm extensions in the main zed binary.
Release Notes:
- Fixed extension panics crashing Zed on Linux
As discussed in the first responders meeting. We have collected a lot of
backtraces from these, but it's not quite clear yet what causes this.
Removing these should ideally make things a bit more stable even if we
may run into panics later one when the faulty anchor is used still.
Release Notes:
- N/A *or* Added/Fixed/Improved ...
This enables optimizations for our own proc-macros as well as some heavy
hitters. Additionally this gates the `derive_inspector_reflection` to be
skipped for rust-analyzer as it currently slows down rust-analyzer way
too much
Release Notes:
- N/A *or* Added/Fixed/Improved ...
The auto update helper already removes these when successful, so these
will always fail in the common case.
Additional replaces a mutable const with a static as otherwise we'll
rebuild the job list on every access
