perf/x86/intel: Add event constraint for CYCLE_ACTIVITY.STALLS_MEM_ANY

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.
