nfp: flower: make the match compilation functions reusable
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.
