[APV] Seams and leaks at boundaries between subdivision levels when using Rendering Layers
See image below to see the issue. We can see a seam and some leak at boundary between two subdivision levels when using Rendering Layers with APV

*Steps to reproduce:*
1. Open test project (.zip attached to this issue), and open the Assets/OutdoorsScene.unity
2. Notice how we are using Rendering Layers, probes inside and outside are assigned different rendering layers.
3. Notice the multiple Probe Volumes to use multiple subdivision levels. Notice the seams at the boundary between two different levels.
\\
*Actual results:*
There is a seam and some leakage at the boundary between multiple subdivision levels. This issue arises because the current anti-seam mechanism does not account for Rendering Layers. During baking, values from boundary probes in the smaller brick are replaced with interpolated values from the larger brick, but this process does not consider Rendering Layers. Probes should only receive contributions from probes with which they share a common Rendering Layer.
*Expected results:*
There is no seam nor leak
