Title: Stability lint checks code from macro expansion.

Closes #17185.

The stability lint will now check code generated by macro expansion. It will allow to detect :
- arguments passed to macros using deprecated (and others) items
- macro expansion generating code using deprecated items due to its arguments (hence the second commit, fixing such issue found in libcollections)

Checking is still done at expansion site, but it will also detect a macro explicitly using a deprecated item in its definition.
