More scaffolding for LegacyTHDispatch. (#14852)
Summary:
1) at::functions are now also exposed in the at::legacy::th namespace and we move relevant calls over to use them (to avoid merge conflicts)
2) LegacyTHDispatch now handles device-type initialization
3) We generate derived LegacyTHDispatchers, e.g. THLegacyCPULongDispatcher, although they are currently empty.
