Even if related, they don't have the same performance impact. To avoid any performance hit, we replace the Diffuse by a Subsurface Closure for legacy EEVEE and use the subsurface closure only where needed for EEVEE-Next leveraging the random sampling. This increases the compatibility with cycles that doesn't modulate the radius of the subsurface anymore. This change is only present in EEVEE-Next. This commit changes the principled BSDF code so that it is easier to follow the flow of data. For legacy EEVEE, the SSS switch is moved to a `radius == -1` check.
