Eliminate collision checks between geometry in rendering BVH.

Browse Source 
Later logic using the `pairable_mask` would catch cases preventing pairing callbacks between geometry. However the collision checks were still taking place, wasting performance.

Here we utilize the `tree_mask` feature of BVH to totally eliminate unnecessary collision checks between geometry.
