GPC_FLUSH_MEM_FAULT
The documentation wrongly called the event as BPU_FLUSH_MEM_FAULT and now
has been fixed. Correct the name in the perf tool as well.

This patch addresses review comments that were given for
705ed549148f ("perf vendor events arm64: Add AmpereOne metrics")
but didn't make it to the original patch [1][2]
Changes include: A fix for backend_memory formula, use of standard metrics
when possible, using #slots, renaming metrics to avoid spaces in the names,
and cleanup.

Per errata AC03_CPU_29, STALL_SLOT_FRONTEND, STALL_FRONTEND, and STALL
events are not counting as expected. The follow up metrics patch will
include correct way to calculate the impacted events.

amperene/cache.json file tried to include L1D_CACHE_LMISS while it
doesn't exist in common-and-microarch.json. While this bug doesn't seem to
cause issue in newer kernels with jevents.py script, it prevents building
older perf tools with the backported patch.
