kunit: add parameter generation macro using description from array
The existing KUNIT_ARRAY_PARAM macro requires a separate function to
get the description. However, in a lot of cases the description can
just be copied directly from the array. Add a second macro that
avoids having to write a static function just for a single strscpy.
