Remove deprecated DB::DeleteFile API references (facebook#13322)

Summary:
Cleanup post facebook#13284.

Pull Request resolved: facebook#13322

Test Plan:
1. We did not find any evidence of breakage in internal pre-release integration pipeline runs after renaming the deprecated API in `9.10`.
2. _To the extent possible_, we manually validated partner use cases of file deletion and confirmed deprecated API is no longer in use.
