Cleanup shader generation code (#10663) 
Shader generation is a mess. This commit cleans some parts up, including dropping remains of HLSL support which was never actually implemented.

Fix MSAA stripes (#9247) 
This only works when shaders are enabled.
The centroid varying avoids that the textures (which repeat themselves out of bounds) are sampled out of bounds in MSAA.
If MSAA (called FSAA in minetest) is disabled, the centroid keyword does nothing.

Simple shader fixes. (#8991) 
1. Pass current camera offset to shader, so shader have access to the global coordinates
2. Pass animation timer to fragment shader. C++ code is already there, just wasn't declared in the shader
3. Delay animation timer wrap-around (from 100s to about 16 minutes)

923a8f1983 Shaders: Remove unnecessary 'if' statements 
Pull if GENERATE_NORMALMAPS == 1 into the template to avoid evaluating
it for each fragment.
Remove if (fogDistance != 0.0).
