net: lan969x: add autogenerated VCAP information

Platform VCAP data for each VCAP instance is auto-generated using an
internal Microchip tool. The generated VCAP data contains information
about keyfields, keyfield sets, actionfields, actionfield sets and
typegroups, which in combination are used to encode and decode rules in
the VCAP.

Add the auto-generated VCAP file lan969x_vcap_ag_api.c and assign the
two structs: lan969x_vcaps and lan969x_vcap_stats to the match data.
