llama 65274b2a4e chore(ci): use prebuilt binaries for cargo-llvm-cov and cargo-nextest (#5141)
## Linked issue (required)

Refs #5134

## Summary / motivation (required)

When running ci, instead of manually compiling cargo-llvm-cov and
cargo-nextest when not cached, this pr pulls them in as prebuilt
binaries instead

## Steps to reproduce (required, use N/A if not applicable)

N/A

## How to test (required)

CI should pass, and running `./check` and `just test --coverage` should
work locally too

### Checklist (minimum)

- [x] I ran `./ninja check` or an equivalent relevant check locally.
- [ ] I added or updated tests when the change is non-trivial or
behavior changed.

### Details

Continuing from
https://github.com/ankitects/anki/issues/5134#issuecomment-4936603431,
we can avoid installing the crates globally when run locally, but in ci
it doesn't really matter so we can use install-action as per normal.
W.r.t nextest's features, all `default-no-update` does is remove its
ability to self-update. Since we're puling in prebuilt binaries during
ci there's no difference

I've left out n2 for now, as without a release workflow on its repo or
on anki's fork, we'd still have to compile it ourselves (caching it can
be unsafe, but it sort of is already cached by setup-rust-toolchain?)

## Scope

- [x] This PR is focused on one change (no unrelated edits).
