When binary files were moved or copied, they weren't being handled properly by the new binary file patcher. This wasn't immediately apparent to me because `git apply` and GNU diff can do their own magic, but when using Apple diff, especially in a non-git repo, this would fail to handle the files properly. This change adds the missing handling for those along with tests. Testing Done: - Ran unit tests. - Set up a test case with moved and copied binary files and verified that patching worked correctly.
