devlink: implement shared buffer occupancy monitoring interface
User needs to monitor shared buffer occupancy. For that, he issues a
snapshot command in order to instruct hardware to catch current and
maximal occupancy values, and clear command in order to clear the
historical maximal values.
Also port-pool and tc-pool-bind command response messages are extended to
carry occupancy values.
