perf vendor events arm64: Update N2/V2 events from source
Update using the new data [1] for these changes:

  * Scale some metrics like dtlb_walk_ratio to percent so they display
    better with Perf's 2 dp precision
  * Description typos, grammar and clarifications
  * Unnecessary metric formula brackets seem to have been removed in the
    source but this is not a functional change
  * New sve_all_percentage metric
