Resolve "incorrect-portions-license" errors: add no license lint to top of GPU files with both licenses (#3965)

Summary:

This is the first diff in enabling linting. I wanted the diff which updates all files to be just the automated command and the .toml config files changes, so this diff is a preparation step.

We need this because we get errors due to having both NVidia and FB license comment headers in the same files. See the errors in D64429711 under "linter-coverage-verification" signal.

Per OSS, we cannot remove the Nvidia notice: https://fb.workplace.com/groups/osssupport/posts/27179779734977284/?comment_id=27181801724775085&reply_comment_id=27181818148106776
