net: microchip: sparx5: Add VCAP debugFS key/action support for the VCAP API

This add support for displaying the keys and actions in a rule.
The keys and action display format will be determined by the size and the
type of the key or action. The longer keys will typically be displayed as a
hexadecimal byte array.

The actionset is not decoded in full as the Sparx5 IS2 only has one
supported action, so this will be added later with other VCAP types.
