Only use persistent buffers to flush on NVIDIA and Windows+AMD (#2489)

Browse source 
It seems like this method of flushing data is much slower on Mesa drivers, and slightly slower on Intel Windows. Have not tested Intel Mesa, but I'm assuming it is the same as AMD.

This also adds vendor detection for AMD on Unix, which counted as "Unknown" before.
