hwcontext_vulkan: actually use the frames exec context for prep/import/export

Browse Source 
This was never actually used, likely due to confusion, as the device context
also had one used for uploads and downloads.
Also, since we're only using it for very quick image barriers (which are
practically free on all hardware), use the compute queue instead of the
transfer queue.
