cc: Map the clip_rect in the SharedQuadState to include the drawTransform of the hosting delegated renderer layer.

The clip rect is assuming that it draws to its old target space, but it will be
drawing to the target space of the delegated renderer layer, so adjust it
accordingly.

Tests:
cc_unittests:DelegatedRendererLayerImplTestSharedData.SharedData
