vo_opengl: add support for linear scaling without CMS
This introduces a new option linear-scaling, which is now implied by
srgb, icc-profile and sigmoid-upscaling.
Notably, this means (sigmoidized) linear upscaling is now enabled by
default in opengl-hq mode. The impact should be negligible, and there
has been no observation of negative side effects of sigmoidized scaling,
so it feels safe to do so.
