[clang] NFCI: Adopt `SourceManager::getFileEntryRefForID()`

This commit replaces some calls to the deprecated `FileEntry::getName()` with `FileEntryRef::getName()` by swapping current usages of `SourceManager::getFileEntryForID()` with `SourceManager::getFileEntryRefForID()`. This lowers the number of usages of the deprecated `FileEntry::getName()` from 95 to 50.
