Summary: Ensures that newly-made `File` objects get indexed into the new ngrams index. Fixes T8788.
Test Plan:
- uploaded a file with daemons stopped; confirmed no new rows in ngrams table
- started daemons; confirmed indexing of previously-uploaded files happened
- uploaded a new file with daemons running; confirmed it got added to the index
Not sure how to test the changes to `PhabricatorFileUploadSource->writeChunkedFile()` and `PhabricatorChunkedFileStorageEngine->allocateChunks()`. I spent a few minutes trying to find their callers, but the first looks like it requires a Diffusion repo and the 2nd is only accessible via Conduit. I can test that stuff if necessary, but it's such a small change that I'm not worried about it.
