cc: Cache the twin tree's layer in PictureLayerImpl.
The PictureLayerImpl uses its twin layer to do various things
and every time it wants to find its twin, it has to go through
the LayerTreeImpl and its hash map.
Specifically, every time we create a Tile, we check make use
of the layer's twin, so we do this same lookup hundreds of times
per layer in order to UpdateTilePriorities.
This change makes PictureLayerImpl compute the twin layer once
and save it.
The ImplSidePaintingPerfTest.HeavyPage perf test shows the
improvement with a 10% reduction in time.
