Live Subdivision Preview appears to do nothing. Needs parenting in UI

Repro:

1. Navigate to the Rendering Debugger (Window > Analysis > Rendering Debugger)
2. Ensure you have some static geometry in the Scene, and a Global Probe Volume
3. From the Probe Volume tab, enable `Live Subdivision Preview`.

 

Observed:

Nothing appears to change in the Scene view. This is confusing to users.

 

Notes:

The reason this happens, is because "Live Subdivision Preview" is incumbent on Display Bricks being enabled. However, it is possible to enable the preview without having the bricks also enabled, which is confusing if users are not aware of this.

This can be easily fixed by making "Live Subdivision Preview" a child of the Display Bricks property, which is only shown when the parent is toggled on.
