TODO [GFX]: Recheck if lods of GPU indirect objects work correctly in light probes

[steaklive]

After adding support for GPU indirect objects' rendering to light probes, I got a feeling that LODs > 0 might be skipped. The code seems correct and GPU culling seems to be working ok for probe's camera views, however, I need to double-check that with debug colors or smth to be sure (its a bit difficult to verify this otherwise in a big scene with thousands of indirect objects and inside a low-res 128x128 specular probe cubemap texture).
