Rollup merge of rust-lang#52004 - kennytm:toolstate-fixes, r=Mark-Simulacrum

toolstate: Fixed detection of changed submodule, and other fixes.

1. Make sure that if a submodule is updated but failed to test-pass, we'll block the merge.
2. Make sure failure on external docs (nomicon/RBE/etc) are properly checked.
3. If the commit message starts with "Update RLS" (or clippy etc), automatically run the "tools" job on the PR, so that we could know if the update failed before merging.
