compiler: Add a new STATE_VAR_ADVANCED_BLENDING_MODE built-in uniform.
This will be used for emulating GL_KHR_advanced_blend_equation features
in shader code. We'll pass in the blending mode that's in use, and use
that in (effectively) a switch statement in the shader.
v2: Use the new _AdvancedBlendMode field.
