net: sparx5: add new VCAP constants to match data

In preparation for lan969x VCAP support, add the following three new
VCAP constants to match data:

    - vcaps_cfg (contains configuration data for each VCAP).

    - vcaps (contains auto-generated information about VCAP keys and
      actions).

    - vcap_stats: (contains auto-generated string names of all the keys
      and actions)

Add these constants to the Sparx5 match data constants and use them to
initialize the VCAP's in sparx5_vcap_init().
