Subject: Add support for clipstack to Gr. GrClip is now a list of rects and
 paths with set operations to combine them. The stencil buffer is used to
 perform the set operations to put the clip into the stencil buffer. Building
 Gr's clip from Skia's clipStack is currently disabled due to the fact that
 Skia's clipStack is relative to the root layer not the current layer. This
 will be fixed in a subsequent CL.
