perf gtk/annotate: Support multiple event annotation 



Show multiple annotation result for each evsel.  Each result represents
the most frquently sampled symbol/function for the evsel and it will be
shown in a tab window.

For this add a reference to main container (notebook) to the pgctx.  At
the first call to annotate browser, hist_entry__find_annotations() will
setup a new browser, and next calls will add new tabs to the browser.
But it requires final perf_gtk__show_annotations() to start processing
GUI events.
