perf tools: Remove hists from evsel
Now tools that deals want to have an hists per evsel need to call
hists__init() before creating any evsels, which can be as early as when
parsing the command line, so do it before calling parse_options().
The current tools using hists/hist_entries are report, top and annotate,
change them to request per evsel hists.
This is in preparation for making evsels usable by 3rd party tools, that
not necessarily live in perf's source code repository.
