Cary Clark 1ea5656a28 Revert "Base Gradient FP Refactor" 
This reverts commit 10f7a1e075.

Reason for revert: broke google3 roll
Original change's description:
> Base Gradient FP Refactor
> 
> --
> 
> Redefines how gradients will be written in the GPU back-end:
> 
> They are split into three fragment processor components: master, layout, and colorizer.
> The layout FP is responsible for converting the fragment position into an interpolant value, t.
> Each high-level gradient--such as linear, radial, etc.--are implemented solely in a layout FP.
> The colorizer FP is responsible for converting t into a color.
> The master FP invokes the layout, clamps t into the proper domain, and then invokes the colorizer.
> GrGradientShader provides factory functions to create FP graphs from SkGradientShader instances.
> This pattern is documented in gpu/gradients/README.md.
> 
> Goals for current CL
> ====================
> 
> Outline the FP components by providing .fp implementations for the simplest gradients.
> Defines a two-color single interval colorizer and a linear gradient layout, and the master effect.
> A MakeLinear() factory function is provided that can convert SkGradientShaders that fit these constraints.
> SkLinearGradient first attempts to use the new system, falling back to the original GrGradientEffect.
> 
> Future CLs
> ==========
> 
> To keep the CL reviews manageable, additional dependent CLs will be added that gradually replace past functionality.
> A CL for each layout will be defined.
> CLs for the different analytic colorizer cases and the textured gradient case will be defined.
> Once the new system supports all current layouts and colorizer capabilities, all old GPU gradient code will be removed.
> After this clean-up, analytic colorization can hopefully be expanded to reduce the usage of textured gradients.
