  [Driver] Ignore non-clang pch files when -include a.h probes a.h.gch (#69204)

Instead of deprecating the "gch probe" as in
f726da1193baf51e0a66453cc32dcffb8a9121d4, this makes clang ignore files
which are not clang pch files (See discussion on PR #67084).

This fixes the issues mentioned in the former patch, with GCC-generated
.gch files getting in the way when using clang, while maintaining the
probing behavior for builds which rely on that.
