Drop `./x suggest`
This PR removes the current `./x suggest` implementation (rust-lang/rust#109933, rust-lang/rust#106249) and associated docs for several reasons:
1. Primarily, `./x suggest` is another "flow" in bootstrap that incurs extra complexity and more invariants that bootstrap has to maintain. This causes more friction when trying to investigate and fix staging problems. As far as I know, this flow has not been actively maintained in quite a while, and I'm not aware of interest in maintaining it. Bootstrap really could use less implementation complexity with a very limited maintenance bandwidth.
2. The current `./x suggest` implementation "bypasses" the usual stage defaults for the various check/build/test/etc. flows, and it's not really possible to have a stage default because `./x suggest --run` produces a *sequence* of suggestions like [`./x check`, `./x test library/std`, ..] and then tries to run all of them in sequence, based on which files are modified.
3. We've not seen a lot of interest both in using it or extending static/dynamic test suggestions. Last extensions were rust-lang/rust#117961 and rust-lang/rust#120763. I'm not convinced the extra implementation complexity is worth it. This was discussed in:
- [#t-infra/bootstrap > Dropping the current `./x suggest` flow implementation](https://rust-lang.zulipchat.com/#narrow/channel/326414-t-infra.2Fbootstrap/topic/Dropping.20the.20current.20.60.2E.2Fx.20suggest.60.20flow.20implementation/with/527456699)

Closesrust-lang/rust#109933 (the current implementation is being removed).
Closesrust-lang/rust#143569 (by removing `./x suggest` altogether).
triagebot.toml: ping lolbinarycat if tidy extra checks were modified
I rewrote a large chunk of this module, and plan to do further changes to it (namely moving rustdoc_js checks into it), so it would be nice to keep up with and provide feedback on any changes to it, at least for the immediate future.

Merge `compiler-builtins` as a Josh subtree
Use the Josh [1] utility to add `compiler-builtins` as a subtree, which
will allow us to stop using crates.io for updates. This is intended to
help resolve some problems when unstable features change and require
code changes in `compiler-builtins`, which sometimes gets trapped in a
bootstrap cycle.
This was done using `josh-filter` built from the r24.10.04 tag:
git fetch https://github.com/rust-lang/compiler-builtins.git 233434412fe7eced8f1ddbfeddabef1d55e493bd
josh-filter ":prefix=library/compiler-builtins" FETCH_HEAD
git merge --allow-unrelated FILTERED_HEAD
The HEAD in the `compiler-builtins` repository is 233434412f ("fix an if
statement that can be collapsed").

I've put myself on vacation a while ago, but really I just want to remove myself from the queue because I couldn't get around to reviewing all the PRs, I'm still here and available :3.
