Bug: skia:10178 These functions can be performed generically using SkRasterPipeline or skcms. Further, the reason we used a function pointer anyway was so that we could call the same function on each row separately. But libwebp's API doesn't let us do a single row at a time anyway. Simplify this method by using readPixels when necessary and skipping conversion entirely when possible. Add support for encoding from unpremul 4444. It is simpler to support it, and it's not obvious why we didn't support it before. Keep the behavior of not supporting A8, and apply the same to the other alpha-only formats. Note that we could support encoding such an image to alpha, r=0, g=0, b=0, but I'd rather leave adding that feature to a separate change, which enables it for all encoders (and accounts for the internal use of PNGs as a round-trip for kAlpha_8_SkColorType). Add GMs to test the newly supported SkColorTypes.
