Improve error message (and investigate causes) for unsuitable GL adapter #6581
Description
With wgpu 0.20 we no longer get crashes in these situations, but whenever there's no available graphics adapter we exit with a less than optimal error message.
One such instance was successfully reproduced by @02alexander:
