Add a simple atlas to the GPU tessellation path renderer

If a path is small and simple enough, we now try to atlas it. There
is only one atlas and it caps at 2048x2048. Once it runs out of room,
everything just draws direct. The atlas is rendered using the existing
GrTessellatePathOp. It provides alpha8 coverage even for msaa render
targets.
