Add missing cull flags when counting intersections of rays with triangle-based cubes

Add a cull flags, so each convex geometry is counted once, instead of twice.

Components: Vulkan

VK-GL-CTS Issue: 2890

Affects:
    dEQP-VK.ray_tracing_pipeline.misc.*stress*
    dEQP-VK.ray_tracing_pipeline.misc.cullmask*
    dEQP-VK.ray_tracing_pipeline.misc.mixedPrimTL
