coresight: perf: traceid: Add perf ID allocation and notifiers

Adds in calls to allocate and release Trace ID for the CPUs in use
by the perf session.

Adds in notifier calls to the trace ID allocator that perf
events are starting and stopping.

This ensures that Trace IDs associated with CPUs remain the same
throughout the perf session, and are only released when all perf
sessions are complete.
