Issue #19700: set __spec__ appropriately in runpy

Browse source 
Note that __spec__.name is not currently guaranteed to be in
sys.modules when the code is running, only __name__ is.

The "running module is in sys.modules" invariant will be
expanded to also cover __spec__.name in a subsequent patch.
