nfp: flower: make the match compilation functions reusable

Browse source

Expose and refactor the match compilation functions so that they
can be invoked externally. Also update the functions so they can
be called multiple times with the results OR'd together. This is
applicable for the flows-merging scenario, in which there could be
overlapped and non-conflicting match fields. This will be used
in upcoming conntrack patches. This is safe to do in the in the
single call case as well since both unmasked_data and mask_data
gets initialised to 0.
