This reverts commit 0f7c10ef56.
Reason for revert: Unhappy rollers
Original change's description:
> Add sRGB 8888 colortype
>
> A color type that linearizes just after loading, and re-encodes to sRGB
> just before storing, mimicking the GPU formats that work the same way.
>
> Notes:
> - No mipmap support
> - No SkPngEncoder support (HashAndEncode's .pngs are ok, though?)
> - Needs better testing
>
> This is a re-creation of reviews.skia.org/392990
>
