gh-109894: Fix initialization of static MemoryError in subinterpreter (gh-110911)

Browse source 
Fixes #109894

* set `interp.static_objects.last_resort_memory_error.args` to empty tuple to avoid crash on `PyErr_Display()` call
* allow `_PyExc_InitGlobalObjects()` to be called on subinterpreter init
