Eric Snow 1e1a30f9f4 [3.12] gh-110310: Add a Per-Interpreter XID Registry for Heap Types (gh-110311) (gh-110714) ...

We do the following:

* add a per-interpreter XID registry (PyInterpreterState.xidregistry)
* put heap types there (keep static types in _PyRuntimeState.xidregistry)
* clear the registries during interpreter/runtime finalization
* avoid duplicate entries in the registry (when _PyCrossInterpreterData_RegisterClass() is called more than once for a type)
* use Py_TYPE() instead of PyObject_Type() in _PyCrossInterpreterData_Lookup()

The per-interpreter registry helps preserve isolation between interpreters.  This is important when heap types are registered, which is something we haven't been doing yet but I will likely do soon.
