RDMA/mlx5: Support optional-counters binding for QPs

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.
