st/mesa: Do GL_RGBA->GL_RGB texsubimage on hardware
State tracker currently backs GL_RGB textures with RGBA almost always.
This means we need to maintain A==1 in these textures to give correct GL_RGB
sampling results.
This change offloads the RGBA->RGB copy to hardware using the new writemask
version of u_blit_pixels.
More src/dstLogical/dstActual triples could be shifted to hardware by
this technique in future patches.
