Revert "Track node mutations (#152389)"

Summary:
This reverts commit c2936ebfd58be7a6519f51d165dfac8407020140.

Reverted pytorch/pytorch#152389 on behalf of https://github.com/jeanschmidt due to Humm, interesting, there seems to be a bug in stack PRs, as it should be part of the stack and be reverted with the other ones ([comment](pytorch/pytorch#152389 (comment)))
