Revert of Screenspace AA tessellated path rendering.

Revert of Screenspace AA tessellated path rendering. (patchset #37 id:730001 of https://codereview.chromium.org/1152733009/ )

Reason for revert:
Causing asserts in GLPrograms test on Mac.

Original issue's description:
> Screenspace AA tessellated GPU path rendering.
> 
> This is an approach to antialiased concave path rendering 
> on the GPU without using MSAA. It uses GrTessellator to 
> extract boundary contours from the given path, then 
> inflates by half a pixel in screen space each direction, 
> then renders the result with zero alpha on the outer
> contour and one alpha on in the inner contour. This 
> requires two passes through the tessellation code: one
> to extract the boundaries, then one to tessellate the
> result.
> 
> This gives approximately a 3X improvement on the IE
> chalkboard demo in non-MSAA mode, a 30-40% improvement 
> on MotionMark's "Fill Paths", and a ~3X improvement on 
> MotionMark's "canvas arcTo segments".
> 
> It works best for large, simple paths, so there's currently
> a limit of 10 verbs in the onCanDrawPath() check. This 
> dovetails nicely with the distance field path renderer's
> support for small, detailed (and cached) paths.
