  [clang][Dependency Scanning] Adding an API to Diagnose Invalid Negative Stat Cache Entries (#135703)

We have had numerous situations where the negatively stat cached paths
are invalidated during the build, and such invalidations lead to build
errors.

This PR adds an API to diagnose such cases.
`DependencyScanningFilesystemSharedCache::diagnoseNegativeStatCachedPaths`
allows users of the cache to ask the cache to examine all negatively
stat cached paths, and re-stat the paths using the passed-in file
system. If any re-stat succeeds, the API emits diagnostics.
