mesa: Add MESA_FORMAT_{A8R8G8B8, X8R8G8B8, X8B8G8R8}_SRGB (v2)
This means that each 8888 SRGB format has a reversed counterpart,
which is necessary for handling big-endian mesa<->gallium mappings.
v2: fix missing i965 additions. (Jason)
fix 127->255 max alpha for SRGB formats. (Jason)
v1: Reviewed-by: Jason Ekstrand <[email protected]>
