Before (code in screenshot is from this branch,
`crates/zed/languages/rust.rs:179`):

Notice how the last 2 entries (that are async functions) are not
highlighted properly.
After:

This is slightly suboptimal, as it's hard to tell that this is an async
function - I guess adding an `async` prefix is not really an option, as
then we should have a prefix for non-async functions too. Still, at
least you can tell that something is a function in the first place. :)
Release Notes:
- Fixed Rust async functions not being highlighted in completions.
See Linear description for the full explanation of the issue. This PR is
mostly a mechanical change, except for the one case where we do pass in
an explicit `next_id` instead of `model_id` in project.rs.
Release Notes:
- Fixed a bug where some results were not reported in project search in
presence of unnamed buffers.

Prepare to remove concept of a runtime from greater server startup code,
which is important for future language server extensibility

This also ensures that, if you load the same language more than once,
a future that resolves to the language (or an error) is returned at
all times. Previously, we would only return it the first time the language
was loaded.
The new version of rust-analyzer changed the disk-based diagnostic token
to `rust-analyzer/checkOnSave/0`. The trailing number could be different
from 0 when there are multiple Rust projects open using the same rust-analyzer
instance.
As such, with this commit we will perform a prefix match as opposed to a strict
equality check when detecting a disk-based diagnostics progress token.
* Use --prefix flag to guarantee that they are installed in .zed
* Use the @latest tag when available
* Extract helper functions
