LOG: Frontend: Migrate to FileEntryRef in CompilerInstance::InitializeSourceManager, NFC

Use `FileManager::getVirtualFileRef` to get the virtual file for stdin,
and add an overload of `SourceManager::overrideFileContents` that takes
a `FileEntryRef`, migrating `CompilerInstance::InitializeSourceManager`.
