Move `needless_pass_by_ref_mut`: `suspicious` -> `nursery`
[Related to [this Zulip thread](https://rust-lang.zulipchat.com/#narrow/stream/257328-clippy/topic/needless_pass_by_ref_mut.20isn't.20ready.20for.20stable)]
`needless_pass_by_ref_mut` has been released with some important bugs (notably having a lot of reported false positives and an ICE). So it may not be really ready for being in stable until these problems are solved. This PR changes the lint's category from `suspicious` to `nursery`, just that.

Fix: Write access check of `prefix` and `sysconfdir`
when DESTDIR is present.
Improvement: Instead of repeatedly reading `DESTDIR` within
each `fn prepare_dir` usage, read it once and pass it to
the `fn prepare_dir`.

Commit 8378487 from #114611 changed the location of an obligation
deduplication step in `opt_normalize_projection_type`. This meant that
deduplication stopped happening on one path where it was still
necessary, causing a couple of drastic performance regressions.
This commit moves the deduplication back to the old location. The good
news is that #114611 had four commits and 8378487 was of minimal
importance, so the perf benefits from that PR remain.
Fixes#116780, #116797.

This should fix running tests on the emscripten target. In the future
it's expected we'll want to entirely remove this builder since it's a
tier 2 target, but for this initially beta-targeted patch keeping the
changes minimal is preferred.
Pass `-jN` from Make to `BOOTSTRAP_ARGS`
Enables the same functionality as `x -jN` in Make by passing the `-jN` arg from Make to the `BOOTSTRAP_ARGS` if it is specified.
Document that Instant may or may not include system-suspend time
Since people are still occasionally surprised by this let's make it more explicit. This doesn't add any new guarantees, only documents the status quo.

I'm not _entirely_ sure about all changes, although I do like all of them. If you'd like I can drop some commits. Best reviewed on a commit-by-commit basis, I think, since they are fairly isolated.
rustdoc: speed up processing of cross-crate fns to fix a perf regression
* The first commit doesn't affect perf but get's rid of a `.clone()` and a bunch of lines of code. I can drop it if you'd like me to
* The second commit, *“reduce the amount of `asyncness` query executions”*, addresses the perf regression introduced in #116084
