Update rapids-build-backend to 0.4, remove `GIT_COMMIT`, `VERSION`, and `_version.py` from `MANIFEST.in` across RAPIDS

[KyleFromNVIDIA]

GIT_COMMIT is now being packaged automatically with rapidsai/rapids-build-backend#68, so we no longer need to specify it manually. _version.py has always been packaged automatically by nature of being a Python file. I'm not entirely sure why VERSION is automatically packaged with no MANIFEST.in, but my best guess is it has something to do with us using dynamic = ["version"], so we can take it out too.

For each PR, we should explicitly check the logs to make sure all of these files are being packaged, in case any of these assumptions don't hold up.
