Vulkan: Migrate trace events and occlusion queries Moved GPU trace event and occlusion query commands that were on the primary command buffer to the SecondaryCommandBuffer (SCB). Putting these commands on outside render pass SCB and flushing those commands to primary on-demand as needed to maintain ordering of commands. For resetQueryPool command used by occlusion query, allow the SCB to queue up that command for inside RenderPass SCB. This avoids ending a renderPass prematurely and allows all outstanding reset commands to be executed before the beginRenderPass command since the resets must occur outside of a renderPass. This is groundwork to simplify the hand-off of SCBs from the main thread to a worker thread. Long-term we'd like a single SCB that can handle both inside and outside renderPass commands at the same time to pass to the worker thread for processing into a primary CB.
