perf report: Add --percent-type option
Set annotation percent type from following choices:
global-period, local-period, global-hits, local-hits
With following report option setup the percent type will be passed to
annotation browser:
$ perf report --percent-type period-local
The local/global keywords set if the percentage is computed in the scope
of the function (local) or the whole data (global). The period/hits
keywords set the base the percentage is computed on - the samples period
or the number of samples (hits).
