This commit is an implementation of RFC 1193 which adds the ability to
the compiler to cap the lint level for the entire compilation session. This flag
will ensure that no lints will go above this level, and Cargo will primarily use
this flag passing --cap-lints allow to all upstream dependencies.

Closes #27259

This message is not very user-friendly, perhaps "Set the most restrictive lint level. More restrictive lints are capped at this level". Or something more concise.
