OcclusionFeedback may not be performant for primitives with large screensize

A licensee reported that the performance could be worse in some scenarios (probably a small scene with large objects) with OcclusionFeedback enabled ( 20fps up if disabled), tested on a Qualcomm 870 with Vulkan. They also reported it improved performance in a large open world.
A possible cause is that OcclusionFeedback is not performant for objects with large bounds.

Skipping primitive occlusion tests if they occupied a large screensize could be a potential fix.
