cache opengl probe results

Description (last modified by Antoine Martin)

It would be nice to be able to probe the opengl state just once and cache the results - this would speedup the client startup.

On Linux, this could be cached by graphics card so that a change in configuration would cause xpra to re-run the opengl probing:

$ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Skylake GT2 [HD Graphics 520] (rev 07)

Looks like this would involve parsing the output of lspci which is going to be slow.. https://github.com/rdobson/python-hwinfo, Python, In linux obtain VGA specifications via lspci or HAL?

Preferably, this cache should be per-host: Get a unique computer ID in Python on windows and linux.
And ideally, we should somehow record the driver version in case a driver update / downgrade breaks things.

Similar to #2349.

Detecting the driver makes this too hard: by the time we get the driver information, we've already done most of the job required for a full opengl device test.
