Note the version and PR of removed features when using it

Fixes rust-lang/rust#141619

I added the diagnostic information. Since all the current version information is present, it prints the version information anyway, as shown in tests/ui. And PR will not print if it is None, we can gradually add the PR links.

Split into two commits for easier review.
