When using OpenGL on Intel ARC the driver reports a max 3d allowed size of 2048. The volume probe will create a texture that doesn't fit in this dimension when selecting a probe size of 512 or 1024 MB. This PR will reshape the volume pool atlas texture until it found a shape that is optimal and fit on the device. When reshaping selects a different pool size a warning message will be displayed as it might change the visual quality. When reshaping the smallest row size will be selected in order to improve the occupancy. Reshaping will only happens when a different setting is set in the `Performance->Memory->Light Probes Volume Pool`.
