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
