Vanilla visuals are not maintained if a gbuffer pass is omitted

What happened?

When creating a shader, the vanilla visuals of Minecraft are not maintained if a specific gbuffer pass is omitted. For example, if gbuffers_skybasic is missing, there are no stars at night; if gbuffers_clouds is missing, the fog is not applied correctly to them; if gbuffers_armor_glint is missing, the glint is then not animated; and so on.

This forces shader developers to do more work than necessary if they wish to keep some parts vanilla, especially since in some cases it's not so trivial to cover all edge-cases with a replacement. It also differs from Optifine, which keeps vanilla visuals in this scenario.
