Include buildfiles in VFS We subscribe to `textDocument/didSave` for `filesToWatch`, but the VFS doesn't contain those files. Before #18105, this would bring down the server. Now, it's only a benign error logged: ``` ERROR notification handler failed handler=textDocument/didSave error=file not found: /foo/bar/TARGETS ``` It's benign, because we will also receive a `workspace/didChangeWatchedFiles` for the file which will invalidate and load it. Explicitly include the buildfiles in the VFS to prevent the handler from erroring.

Fixes #18055, if a client sends us an unregistered document path in a did save notification it would force us to exit the thread. That is obviously not great behavior, we should be more fallible here
