Re-enable some functionalize tests (#82363)
As far as I can tell, #81145 got merged (
https://github.com/pytorch/pytorch/pull/81145 was reverted, but the
revert was reverted https://github.com/pytorch/pytorch/pull/82189)
These tests were originally disabled to coordinate a merge across
pytorch/pytorch and pytorch/functorch repos, since the PR got merged we
can reenable these tests.
It is a little fishy that nothing had to change, but all the tests seem
to pass.
Fixes https://github.com/pytorch/functorch/issues/974
