Make strict modules appear as normal modules

Summary:
There's a big perf difference when getting the source info for a strict module vs a normal module: https://fb.workplace.com/groups/653235072286882/permalink/1791930228417355/

This is because `getmodule` gets a lot more complicated when things aren't modules: https://www.internalfb.com/code/fbsource/[630a7e128132fa049cea4b73d9d9eb079e0608d6]/third-party/python/3.12/Lib/inspect.py?lines=988

This does the same strict to make our StrictModule test as a normal module for `isinstance` that we use with generators.
