cc: Without valid frame, delegated renderer layer is not drawable

When the frame has no render passes, or is empty sized, then the
delegated renderer layer passes an empty DelegatedFrameData to the
impl tree and is considered !drawsContent().

Tests:
LayerTreeHostDelegatedTestLayerUsesFrameDamage.runSingleThread
LayerTreeHostDelegatedTestLayerUsesFrameDamage.runMultiThread
