Add StrPromise and StrOrPromise aliases to django_stubs_ext.

We re-export StrPromise and StrOrPromise explicitly making it available
via django_stubs_ext so that conditional imports with TYPE_CHECKING is
not required. These aliases fall back to Promise or Union[str, Promise]
when not TYPE_CHECKING.
