[clang] Reset FileID based diag state mappings (#143695)
When sharing same compiler instance for multiple compilations, we reset
source manager's file id tables in between runs. Diagnostics engine
keeps a cache based on these file ids, that became dangling references
across compilations.
This patch makes sure we reset those whenever sourcemanager is trashing
its FileIDs.
