Break up large test suites (#50458)

Browse source 
This breaks up some of our longest running tests which allows more
parallelizing of the tests. This also moves turbopack tests filtering
back to an allow list as it is running a lot of unrelated tests
currently which isn't ideal. We should only be running against tests
that are explicitly testing turbopack e.g. build tests should not be
duplicated in the turbopack group.
