net/mlx5: HWS, rework the check if matcher size can be increased

Browse source

When checking if the matcher size can be increased, check both
match and action RTCs. Also, consider the increasing step - check
that it won't cause the new matcher size to become unsupported.

Additionally, since we're using '+ 1' for action RTC size yet
again, define it as macro and use in all the required places.
