perf vendor events arm64: Categorise the Neoverse V1 counters

This is so they are categorised in the perf list output.  The pmus all
exist in the armv8-common-and-microarch.json and arm-recommended.json
files, so this commit places them into each category's own file under

  tools/perf/pmu-events/arch/arm64/arm/neoverse-v1

Also add the Neoverse V1 to the arm64 mapfile
