gh-102660: Handle m_copy Specially for the sys and builtins Modules (gh-102661)

Browse source 
It doesn't make sense to use multi-phase init for these modules. Using a per-interpreter "m_copy" (instead of PyModuleDef.m_base.m_copy) makes this work okay. (This came up while working on gh-101660.)

Note that we might instead end up disallowing re-load for sys/builtins since they are so special.
