QmlProfiler: Rebuild the flamegraph model when visible features change

Browse Source 
This is more expensive than just setting the filtered items' height to
0. However, this way we implicitly also change the size of the root
element, group equal items that end up on the same level by filtering,
recalculate the cutoff for too small items and resort all items by
width.
