perf hists: Introduce hist_entry__filter()
The hist_entry__filter() function is to filter hist entries using sort
key related info. This is needed to support hierarchy mode since each
hist entry will be associated with a hpp fmt which has a sort key. So
each entry should compare to only matching type of filters.
To do that, add the ->se_filter callback field to struct sort_entry.
This callback takes 'type' argument which determines whether it's
matching sort key or not. It returns -1 for non-matching type, 0 for
filtered entry and 1 for not filtered entries.
