userns: Add KUnit test suite for uid_gid_map
Add a KUnit test suite to verify the insertion and sorting of mappings
in struct uid_gid_map. This test suite validates both base extent
insertion (<= 5 mappings) and extended extent insertion (> 5 mappings,
which triggers the allocation of the forward and reverse pointers).
This is especially useful for verifying that the __counted_by_ptr
attribute added to 'forward' and 'reverse' pointers works correctly
without causing any runtime bounds-checking panics or traps.
