* Disabled occlusion culling for WaterDepth capture camera. (To workaround issue on Quest)

* Changed samplers for water depth and scene depth to workaround Quest issue. (Quest uses point sampler pre the change)
* Added inverseZ handling to waterDepth map.
* Comment out unused code in WaterLighting.hlsl
