perf/x86/intel: Constrain Panther Cove UOPS_DISPATCHED events to PMCs 0-3
Per the latest Panther Cove event definitions, the following events are
only supported on PMCs 0-3:
- UOPS_DISPATCHED.INT_EU_ALL (0x1b2)
- UOPS_DISPATCHED.ALU (0x2b2)
Add explicit event constraints for these two events so scheduling does
not place them on unsupported counters.
