 - Improve performance of tessellation control pipeline stage by processing multiple 
   patches per workgroup.
 - `vkCmdBindDescriptorSets` order `pDynamicOffsets` by descriptor binding number 
   within each descriptor set.
 - `vkCmdCopyImage` on macOS flush non-coherent image memory before copy operation.
