selftest: netdevsim: Add resource dump and scope filter test

Browse Source 
Add resource_dump_test() which verifies dumping resources for all
devices and ports, and tests that scope=dev returns only device-level
resources and scope=port returns only port resources.

Skip if userspace does not support the scope parameter.
