Codegen: ADInplaceOrViewType only include operators registered (#68692)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/68692
ADInplaceOrViewType is a sharded file, so by only including specific
operator headers, we ensure that changing one (non-method) operator
only needs one shard to be re-compiled.
This also ports the generated code over to the `at::_ops` interface,
and the code generator itself to using `write_sharded` instead of
re-implementing its own version of sharding.
