GrTessellator: abstract vertex allocation into caller.

This abstracts all vertex allocation out of GrTessellator via a VertexBuffer interface. This removes all GPU-related calls from GrTessellator.

It also factors vertex drawing into GrTessellatingPathRenderer::drawVertices(), and makes tessellate() (now draw() also responsible for drawing. This means the cache hit case is clearer as an early-out,
and storing into cache is done in draw() as well.
