Brian Osman 2b23c4bf31 Dest color space no longer impacts mipmaps or texture sampling
PS5: Removes SkDestinationSurfaceColorMode, tracking of mipmap
mode on GrTexture, sRGB decode state per-texture. Because we
were often choosing sRGB configs for RGB color types, legacy
rendering would then be incorrect (too dark). So...

PS7: Stops ever using sRGB pixel configs when translating
image info or color type. Also removes a bunch of GrCaps bits
and a GrContextOption that are no longer relevant.

PS9: Adjusts surface creation unit test expectations, and
changes the raster rules accordingly.

At this point, sRGB configs are (obviously) going to be broken.

Locally, I ran 8888, gl, and the gbr- versions of both. Across
all GMs x configs, there are 13 diffs. 12 are GMs that create
surfaces with a color-space attached (and thus, the offscreen
is no longer getting sRGB pixel config). The only remainder
constructs an SkPictureImageGenerator, (with an attached color
space) and renders it to the gbr-gl canvas, which triggers a
a tagged surface inside the generator.
