llvmpipe: reorganize transfer usage

Move transfer creation and mapping to the "scene" object, and out of
the rasterizer.  The rasterizer operates on already-mapped
framebuffers only, and no longer needs a screen or context pointer.

The scene object has access to a pipe_context, and this reorg prepares
for moving transfer functionality from the screen to the context.
