A new decal all-in-one blend mode with the following functionality.

Normals -> Blend with underlying normals instead of replacing them

Ambient occlusion -> Multiply with underlying

Metallic -> Look at metallic value of both and take whichever value is higher (Lighten)

Roughness -> Multiply with underlying

if Metallic = 1 also:

Color -> replace with underlying value

Dude, we need decals to work in forward renderer properly first before any new updates on the existing one in deferred! :).
