Enforce c10-fullness for all ops (#49619)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/49619
This is a minimal-change PR that enforces that all operators are c10-full by making it the default.
This does not clean up any code yet, that will happen in PRs stacked on top. But this PR already ensures
that there are no non-c10-full ops left and there will be no non-c10-full ops introduced anymore.
