Fixing shader compilation error when writing to FOG when render_mode fog_disabled.
...
Always declares FOG variable regardless of fog state. Previously, only declared
fog if FOG_DISABLED was undefined. This caused errors if the code tried to
write to fog later. Exists as a dummy variable when unused.

Apply PREMUL_ALPHA_FACTOR only in non-split-specular shader variants.
...
This avoids a shader compile error when using SSS and PREMUL_ALPHA_FACTOR in the same shader.
This doesn't change any functionaility, since in practive, the split-specular shader variant is only ever used for opaque objects while using premul alpha makes the object non-opaque

Revise fog blending to fix over-darkening/borders.
...
This can result in low fog densities being a bit brighter, which may need slight adjustment in your scenes.
In exchange, volumetrics now blend smoothly together with the scene and regular fog.

Fix a few improper memory accesses in the clustered forward vertex shader

draw_call.instance_index should not be used directly since it doesn't take into account auto-batching
scene_data_block.data should not be used directly in the vertex shader since it can change between frames and impact motion vector generation
IN_SHADOW_PASS can only be accessed inside functions, so it needs to be a global and not a constant
