[Linux][X11] Editor Graphics API can't be set to OpenGL when running on an Nvidia Optimus laptop, prime offload enabled, and while using X11
Reproduction steps:
1. Create a new 3D project
2. Observe the used Graphics Backend
3. Click Edit > Project Settings… > Player > Other Settings
4. Switch Graphics Backend to OpenGL
5. Observe the used Graphics Backend
Expected results: Project is opened with OpenGL Graphics Backend
Actual results: Project is opened with Vulkan Graphics Backend and “Could not find compatible OpenGL core profile version” error is thrown. Switching to Vulkan Graphics Backend restarts the Editor with Vulkan Graphics Backend

- Graphics Settings shows default values instead of the real values in the Rendering Debugger when Volume.profile is assigned via script

Resolution Note:
Seems to be an underlying issue with Ubuntu's nvidia offload support in 22.04 and appears to be fixed in 24.04.
Since the editor still continues to launch with vulkan and this occurs on a narrow set of OS versions and hardware, we're going to choose to not fix this issue.
