Fix clipping/culling for DelegatedRendererLayer*
OcclusionTracker::unoccludedContentRect was assuming that transform and clip for
the quads matched the one from the layer, which is not true for delegated quads.
Instead, explicitly pass transform & clip, and keep the old behavior as
unoccludedLayerContentRect for tests.
