Add support to allow optional-counters binding to a QP, whereas when a bind operation is requested depending on the counter optional-counter binding state the driver will determine if to also add optional-counters to this QP binding. The optional-counter binding is done by simply adding a steering rule for the specific optional-counter condition with the additional match over that QP number. Note that optional-counters per QP rules are handled on an earlier prio than per device counters, and per device counter correctness is maintained by core whereas it is responsible to sum active counters when checking device counter and to add them to history count when they are deallocated.
