Vulkan compute: combine all minmax calls

Browse source 
This commit combines the minmax execution via Vulkan compute. The
previous implementation executed compute in vulkan_minmax with a new
command buffer each time. This implementation combines all required
executions of compute in vulkan_minmax in a single command buffer and
uses a pipeline to ensure the enqueued compute calls stay in order.
