[Linux] Can't generate lighting with lightmapper set to Progressive GPU when using AMD or Nvidia GPUs
Reproduction steps:
1. Create a new project from the “3D Sample Scene (HDRP)” template
3. Click Window > Rendering > Lighting
4. Set Lightmapper to "Progressive GPU"
5. Click "Generate Lighting"
Expected result: Lightmapper is set to "Progressive GPU", no OpenCL errors are printed to the logs or console and it is possible to generate lighting
Actual result: Every time Lightmapper is set to "Progressive GPU" it is reset to "Progressive CPU" and OpenCL errors are printed to the Console, with more information in the log file.
Reproduced with: 2021.3.24f1, 2022.3.16f1, 2023.2.7f1, 2023.3.0a12
