Add a tidy check to enforce that all `compiler/*/Cargo.toml`contains `lints.workspace = true`

[jieyouxu]

To consistently enforce lints across all compiler/ crates after #138084.

I.e. check that all compiler crates have

[lints]
workspace = true

see #138084 (comment) #138084 (comment).

See also #138106; note that this is only applicable for non-tool lints (i.e. not for rustc::xxx internal tool lints).

Actually, closing this as stale since we probably can't go the workspace lint approach due to root manifest not being in rustc-src problems.
