Subject: Tracing: CtfVisualizer: Add menu to restrict view to certain threads

Add a new dropdown menu to select which threads should be displayed.
If no threads are selected, all are shown (this is why the word
'restriction' was chosen). At the moment this only affects the
timeline view, see the follow up for the statistics view.
