Vulkan: add GPU trace events RendererVk now tries, as best as it can, to match the CPU and GPU timers on init as well as every finish(). A clock-sync event is generated for each such synchronization point. RendererVk::traceGpuEvent() is a new function that, given a command buffer, performs timestamp queries corresponding to GPU events. These queries are read back when done, without incurring GPU bubbles, at which point an event is generated with that timestamp.
