Revert "Support combining per-vertex coverage with color in default GP vertex shader"
This reverts commit 8e13f69262eeb01e926df4eb79e89615cc741be5.
Reason for revert: Layout tests still failing.
Original change's description:
> Support combining per-vertex coverage with color in default GP vertex shader
>
> Leverage this in ops that use tessellation with per-vertex coverage, to
> move the (color * coverage) work into the vertex shader.
>
> For the tessellating path renderer, color is always uniform, but we were
> sending it per-vertex. Added support to the default GP for routing the
> uniform color to the vertex shader (when there is per-vertex coverage and
> coverage can be folded into alpha). The end result is that we do less work
> on the CPU, and send less data (for incompatible blend modes) or the same
> amount (for compatible blend modes).
>
> Finally, because color is never sent through a vertex attribute, this
> solves wide color (and avoids the vertex bloat that would have happened
> when using half-floats). For the linearizing convex path renderer, do the
> usual fix for wide color.
>
> PS6 is the "clean" version of this CL, later versions are guarded to
> rebaseline layout tests.
