perf hists: Add support for showing relative percentage
When filtering by thread, dso or symbol on TUI it also update total
period so that the output shows different result than no filter - the
percentage changed to relative to filtered entries only. Sometimes
this is not desired since users might expect same results with filter.
So new filtered_* fields to hists->stats to count them separately.
They'll be controlled/used by user later.
