Helps with #94829.

For now this needs you to manually opt in with cargo run --manifest-path src/bootstrap/Cargo.toml -p bootstrap-shim.

Regarding to #102282 (comment)

Right now it doesn't actually save any time, because the shim depends on all of bootstrap's dependencies, but I think we can cut down the shim's dependencies to essentially 0 in a follow-up.

Since this is one of the long-term defined task, I believe this should be done in a seperated PR as a seperated task. bootstrap-shim is currently built on top of MinConfig and Flags which are defined in bootstrap tree.

Right now bootstrap-shim doesn't accept any arguments (oops):

This should work just fine with this PR.

This is non-trivial to fix with the current arg-parsing setup: either we'd have to share flags.rs between bootstrap and bootstrap-shim (which I'd rather not do to cut down on compile times), or we'd have to switch to a different arg-parsing library.

I used Flags in bootstrap shim, not just because of fixing the arg passing bug, but also for easier way to set MinConfig specific flags/options without parsing flags from arguments twice. We already parse flags in Config::parse and we need them in MinConfig::parse as well.

We should add a download-bootstrap # bool option to config.toml to tell bootstrap-shim to fall back to using python instead.

I am not sure if this should be covered in this PR.

The correct syntax is @rustbot ready, not the other way around.

src/tools/x was changed. Bump version of Cargo.toml in src/tools/x so tidy will suggest installing the new version.

#107812 (comment) seems still unresolved here, but it may merit more synchronous discussion - I feel like we're not yet aligned in fact (even if there's no objections) on the exact trajectory here, and that makes me reluctant to merge PRs that create future implications (in particular I still don't think the comments align with a global install).

I agree, let's talk about this on the next team meeting.

[wip] Add bootstrap-shim and package it on nightly
ea813a0 
- Pass `dist bootstrap-shim` explicitly in CI

 This makes it possible to run `dist bootstrap` without also building
 bootstrap-shim, and more importantly works around a bug where currently
 two steps aren't allowed to have the same path.

- Add `check::BootstrapShim`
- [wip] start unifying parsing for Config and MinimalConfig
