Fix rustbuild --color conflict when building on Travis outside of Docker
When trying to build rust on Travis without using `stamp` or `docker`, both `RUSTC_COLOR=1` and `TRAVIS=true` will separately pass `--color always` to the command line. This causes the build to fail due to "*Option 'color' given more than once*".
In this PR, the `RUSTC_COLOR=1` will not be passed in the CI environment.
rustbuild: Build stage 1 error index generator at stage 0
At stage 1 rustdoc is built at stage 0 so the error index generator should be as well.
This fixes `x.py --stage 1 doc` as rustdoc doesn't even build at stage 1.
It was broken by #44605.

rustbuild: Compile rustc with ThinLTO
This commit enables ThinLTO for the compiler as well as multiple codegen units.
This is intended to get the benefits of parallel codegen while also avoiding
any major loss of perf. Finally this commit is also intended as further testing
for #45320 and shaking out bugs.
rustc: Move bytecode compression into codegen
This commit moves compression of the bytecode from the `link` module to the
`write` module, namely allowing it to be (a) cached by incremental compilation
and (b) produced in parallel. The parallelization may show up as some nice wins
during normal compilation and the caching in incremental mode should be
beneficial for incremental compiles! (no more need to recompress the entire
crate's bitcode on all builds)

ci: Update musl with new release
Apparently there's at least one CVE fixed in the new version of musl, and
because we're distributing it seems like a good opportunity to update!
Unfortunately it looks like #38618 still hasn't been fixed.
rustbuild: Don't try to build rustdoc API docs with compiler docs
rustdoc is built separately to rustc now so the docs would need to be
generated separately as well. Also rustdoc doesn't build at stage 1
which prevented the compiler docs being built at stage 1.
Fixes: #44629
At stage 1 rustdoc is built at stage 0 so the error index generator should be as well.
This fixes `x.py --stage 1 doc` as rustdoc doesn't even build at stage 1.
Reactivate clippy in toolstate.toml
The `Cargo.lock` changes are b/c clippy is not its own workspace anymore, but is part of the main workspace
