Robert Phillips 9c5063271a Add skgpu::BlendInfo 
This unifies GrXferProcessor::BlendInfo and SkPipelineDataGatherer::BlendInfo.

The motivation for this is that I want to store a blend info on the
SkPaintParamsBuilder and having the BlendInfo in SkPipelineDataGatherer
made that difficult. Once moved to Blend.h it didn't make sense to have
the GrXferProcessor version.
