Lukas Wirth c69912c76a Forbid std::process::Command spawning, replace with smol where appropriate (#38894)
std commands can block for an arbitrary duration and so runs risk of
blocking tasks for too long. This replaces all such uses where sensible
with async processes.

Nia 11041ef3b0 perf: Greatly expand profiler (#38584)
Expands on #38543 (notably allows setting importance categories and
weights on tests, and a lot of internal refactoring) because I couldn't
help myself. Also allows exporting runs to json and comparing across them. See code for docs.

Nia 782058647d tests: Add an automatic perf profiler (#38543)
Add an auto-profiler for our tests, to hopefully allow better triage of
performance impacts resulting from code changes. Comprehensive usage
docs are in the code.

Currently, it uses hyperfine under the hood and prints markdown to the
command line for all crates with relevant tests enabled. We may want to
expand this to allow outputting json in the future to allow e.g.
automatically comparing the difference between two runs on different
commits, and in general a lot of functionality could be added (maybe
measuring memory usage?).

It's enabled (mostly as an example) on two tests inside `gpui` and a
bunch of those inside `vim`. I'd have happily used `cargo bench`, but that's nightly-only.
