Refs #32668 -- Simplified get_test_modules() in runtests.py.

Browse Source 
This simplifies runtests.py's get_test_modules() in a few ways.  For
example, it changes the function to yield strings instead of returning
pairs of strings, which simplifies the calling code.

This commit also changes SUBDIRS_TO_SKIP from a list to a dict since
the directories to skip depend on the parent directory.
