[issue18115] Use importlib.util.module_to_load in all loaders in importlib

[Brett Cannon]

New submission from Brett Cannon:

BuiltinImporter, FrozenImporter, and ExtensionFileLoader all have their own custom code to manage clearing sys.modules if something goes wrong. Should see if any of them would break if they used importlib.util.module_to_load. And if they would break thanks to any pre-existing module in sys.modules, then add a keyword argument to suppress creating a new module.
