perf/x86/intel: Add event constraint for CYCLE_ACTIVITY.STALLS_MEM_ANY
commit 306e3e91edf1c6739a55312edd110d298ff498dd upstream. The event CYCLE_ACTIVITY.STALLS_MEM_ANY (0x14a3) should be available on all 8 GP counters on ICL, but it's only scheduled on the first four counters due to the current ICL constraint table. Add a line for the CYCLE_ACTIVITY.STALLS_MEM_ANY event in the ICL constraint table. Correct the comments for the CYCLE_ACTIVITY.CYCLES_MEM_ANY event.
