The upcoming PERFCNTR_CONFIG ioctl will allow for both global counter collection, and per-context counter reservation for local (ie. within a single GEM_SUBMIT ioctl) counter collection. Any number of contexts can reserve the same counters, but we will need to ensure that counters reserved for local counter collection do not conflict with counters used for global counter collection. So add tracking for per-context local counter reservations.
