[BUG-232955] Sun/moon projector not occluded by solid objects in reflections

[sl-service-account]

What just happened?

The sun/moon creates a specular highlight through an object which blocks its view and casts shadows.

What were you doing when it happened?

I created a large mesh sphere with inward facing normals as a sky dome. This behaves fine in other testing with the legacy rendering pipeline. With a reflection probe and metallic=1 sphere on the inside, it looks great except the sun or moon cause distracting and incorrect glint on the reflective sphere.

What were you expecting to happen instead?

I expect the specular highlight from the sun/moon projector to be absent since an opaque, shadow casting object completely blocks the view of this light.
