Expand both colorspaces and backends tested by "ColorSpaces" jobs

This CL adds the following to the ColorSpaces jobs:

   CPU: srgb2-rgba, srgb2-f16
   Ganesh GL: gl, narrow-gl, srgb2-gl, glf16, narrow-glf16, srgb2-glf16
   Ganesh Metal: srgb2-mtl, srgb2-mtlf16
   Graphite: srgb2-grmtl, srgb2-grmtlf16

This CL removes the following from the BonusConfigs jobs:

   CPU: srgb-rgba, srgb-f16

This CL removes the following configs from the general bot jobs:

   GPU: srgb-gl, srgb-gles

Note: the srgb -> srgb2 name change is so we can (continue) to Ignore
the plethora of existing "srgb" images in Gold but allow the new
"srgb2" images to be triaged.
