clang-tidy "notes" applying to excluded files can appear for non-excluded files (and possibly causing incorrect warning filtering)

[sean-mcmanus]

If a clang-tidy warning occurs that is followed by another warning that is excluded that has "notes", the notes can get associated with the non-excluded warning instead of the excluded warning, causing the "note" to appear attached to the wrong warning.

This can also cause warnings to be incorrectly filtered out if the "notes" is an "expanded from macro" or "Calling" type.
