net: microchip: sparx5: Adding KUNIT tests of key/action values in VCAP API

This tests that the available keyfield and actionfield add methods are
doing the exepected work: adding the value (and mask) to the
keyfield/actionfield list item in the rule.

The test also covers the functionality that matches a rule to a keyset.
