Remove unecessary stage0 packages

Historically quite a few packages had to be stage0 as they depended on
`template-haskell` and that was stage0. In #23536 we made it so that was
no longer the case. This allows us to remove a bunch of packages from
this list.

A few still remain. In particular `os-string` is a new package and hence
isn't bundled with boot compilers. Once that becomes widespread we can
remove even more!

Resolves #24652
