Revert "More SkVertices implementation work"

This reverts commit 14583e11fd622c686993b741499060a6f3527055.

Reason for revert: leaking

Direct leak of 499104 byte(s) in 2112 object(s) allocated from:
    #0 0x1e195f0 in operator new(unsigned long) (/b/swarm_slave/w/irazbR79/out/Debug/dm+0x1e195f0)
    #1 0x3142b0a in SkVertices::Builder::init(SkCanvas::VertexMode, int, int, SkVertices::Sizes const&) (/b/swarm_slave/w/irazbR79/out/Debug/dm+0x3142b0a)


Original change's description:
> More SkVertices implementation work
> 
> - change virtuals to take const SkVertices*, as we do for TextBobs and Images
> - override onDrawVerticesObject in recording canvases
> - deserialize raw-vertices into SkVertices object
> 
> Possibly a follow-on would intercept the raw-form directly in canvas,
> and remove the virtual, and only support the object form.
