net: microchip: vcap api: Convert multi-word keys/actions when encoding

The conversion to the platform specific multi-word format is moved from the
key/action add functions to the encoding key/action.
This allows rules that are disabled (not in VCAP HW) to use the same format
for keys/actions as rules that have just been read from VCAP HW.
