Update 2pt conical gradient in raster pipeline
The updated algorithm matches our new GPU algorithm
(https://skia.org/dev/design/conical) and it brings
about 7%-26% speedup. In the next CL, I'll simplify
the GPU code by reusing the CPU code in this CL.
7.20% faster in gradient_conical_clamp_hicolor
8.94% faster in gradient_conicalZero_clamp_hicolor
10.00% faster in gradient_conicalOut_clamp_hicolor
11.72% faster in gradient_conicalOutZero_clamp_hicolor
13.62% faster in gradient_conical_clamp_3color
16.52% faster in gradient_conicalZero_clamp_3color
17.48% faster in gradient_conical_clamp
17.70% faster in gradient_conical_clamp_shallow
20.60% faster in gradient_conicalOut_clamp_3color
20.98% faster in gradient_conicalOutZero_clamp_3color
21.79% faster in gradient_conicalZero_clamp
22.48% faster in gradient_conicalOut_clamp
26.13% faster in gradient_conicalOutZero_clamp
