Enable Ganesh dithering
We currently build Skia with SK_IGNORE_GPU_DITHER, effectively disabling GPU dithering.
Remove the build flag to align Ganesh with the sw rasterizer dithering behavior.
Note: Blink only sets the SkPaint dither flag for gradients at this time.
Aside from the flag change, this CL includes:
* a handful of trivial layout tests rebaselines
* some Canvas layout/unit test adjustments (relaxed exact pixel value checks to
accommodate dithering)
* a couple of trivial GPU pixel test rebaselines
