Vulkan: Implement command re-ordering. This introduces a new CommandBufferNode class. Nodes are linked together to form a graph based on their dependencies. When the app triggers a readback or swap, the graph is flushed entirely. This sends the queued ANGLE Vulkan work to the Vulkan queue which is then processed on the GPU with the right dependencies. This design allows us to save on some unnecessary RenderPass creation and also allows us to know what load/store ops to use. It also allows us to take advantage of the Vulkan automatic RenderPass transitions for performance. Load/Store ops and automatic transitions will be implemented in later patches.
