[Mesa-stable] [PATCH] radv: use separate bind points for the dynamic buffers

[Samuel Pitoiset]

The Vulkan spec says:

   "pipelineBindPoint is a VkPipelineBindPoint indicating whether
    the descriptors will be used by graphics pipelines or compute
    pipelines. There is a separate set of bind points for each of
    graphics and compute, so binding one does not disturb the other."
