perf vendor events arm64: AmpereOne/AmpereOneX: Mark LD_RETIRED impacted by errata

Atomic instructions are both memory-reading and memory-writing
instructions and so should be counted by both LD_RETIRED and ST_RETIRED
performance monitoring events. However LD_RETIRED does not count atomic
instructions.
