Prepare sRGB encoding conversion for the removal of GrPixelConfig
Standardizes that GrGpu subclass's onRead/WritePixels never do sRGB<->linear conversion. This means that they can eventually take a color type rather than config. It also means direct callers of GrGpu::read/writePixels can never expect conversion (which in practice is no change).
Consolidate logic about whether to do sRGB<->linear encoding conversions in GrContext::read/writeSurfacePixels helpers. No change in when conversions are done (yet). This prepares this logic to operate on SkColorSpace and color type rather than config WRT the CPU data.
