[subinterpreters] Static types incorrectly share some objects between interpreters #94673

awaiting core review

gh-94673: Hide Objects in PyTypeObject Behind Accessors #104074

Make __mro__ a getter.

Add the fields to static_builtin_state.

Fix type_get_bases() and type_get_mro().

Fix _PyStaticType_InitBuiltin() for subinterpreters.

Call _PyType_CheckConsistency() after setting the fields.

Re-run most of type_ready() under each interpreter.

🔨 test-with-buildbots

Add some comments.

Drop an old workaround for previously shared objects.

🔨 test-with-refleak-buildbots

Move Py_TPFLAGS_READYING to each interpreter for static builtin types.
