gh-95795: Move types.next_version_tag to PyInterpreterState (gh-102343)

Browse source 
Core static types will continue to use the global value.  All other types
will use the per-interpreter value.  They all share the same range, where
the global types use values < 2^16 and each interpreter uses values
higher than that.
