Respect a Layer's (e.g. SurfaceTexture) colorSpace when compositing

This CL extracts the android_dataspace from the GLConsumer and converts
it to a SkColorSpace.  HWUI always expects to composite into an sRGB
destination so when we draw the layer we run the draw through a
colorFilter that converts the input colorSpace into that of the
destination.
