Switch CPPCHECK to broad coverage with excludes (#19909)

Switch lintrunner cppcheck include pattern to include all files and rely
on the exclude pattern to not lint files.

This has the positive side effect that new files would be included in
the linting and the exclude list can have a nice sorting and comments
why things have ended up there.

The end goal should of course be a empty exclude_patterns list.
