perf vendor events: Add Arm Neoverse V2 PMU events

Rename the neoverse-n2 folder to make it clear that it includes V2, and
add V2 to mapfile.csv. V2 has the same events as N2, visible by running
the following command in the ARM-software/data github repo [1]:

  diff pmu/neoverse-v2.json pmu/neoverse-n2.json | grep code

Testing:

  $ perf test pmu

  10: PMU events                                           :
  10.1: PMU event table sanity                             : Ok
  10.2: PMU event map aliases                              : Ok
  10.3: Parsing of PMU event table metrics                 : Ok
  10.4: Parsing of PMU event table metrics with fake PMUs  : Ok
