Force Qt to use GLES if desktop GL is not available
...
Some platforms like the VisionFive 2 don't have working desktop GL,
so they must use GLES to be able to render at all. Qt doesn't try
to fall back if it fails to find a compatible EGL config, so we must
do so ourselves.

Use EGL+GLES workaround for Nvidia X11
...
We can avoid disabling EGL entirely by forcing Qt to use GLES,
which is not impacted by the black window issue. This lets us
simplify back to EGL everywhere.

Use EGL_VENDOR instead of NV-CONTROL for Nvidia detection
...
The latter will still match on a hybrid system when the iGPU's EGL
implementation is in use. This scenario works properly with EGL
rendering in Qt and SDL, so we want to allow that.
