Fix for https://fogbugz.unity3d.com/f/cases/1263298/
Issue slightly trickier to track than I thought.
Looking in C++ it looks like the disc radius is nothing else but areaSize.x, what that mean is that if we ever update that we override the disc radius.
Now, because we handle the area and tube in HDRP, we have our own HDRP-side shape that we then link up with the legacy light. However, for disc light we don't handle the shape ourselves, hence if we update the legacy areaSize with our own shape size, we end up using values from rectangle/tube for the disc and since those are not modified by the inspector, the radius will never change.
Fix is simple, let builtin handle everything about disc and therefore don't update areaSize with our data.
What have I tested: The repro case now works, the rectangle and tube still work. Note the values set from one type of area lights are propagated to different types, this is expected and is coherent with what builtin does.
