gl_shader_manager: Remove reliance on global accessor within MaxwellUniformData::SetFromRegs()

Browse Source 
We can just pass in the Maxwell3D instance instead of going through the
system class to get at it.

This also lets us simplify the interface a little bit. Since we pass in
the Maxwell3D context now, we only really need to pass the shader stage
index value in.
