Turn the recorder thread back on by default on AMD GPUs

The AMD device losses with the recorder (#5, #40) stopped after objects
were kept until their submission completed and the recorder began ending
its own parts; RDNA 1 and 2 cards in #5 ran with vk_recorder on and off.
vk_recorder = 0 still turns it off.
