Group GPU scopes by Vulkan queues instead of CPU thread

[spnda]

With the current profiler, when I submit to two Vulkan GPU queues from 16 threads this will show 16 GPU timelines in the profiler for work to be done. However, I only have two Vulkan queues, and would like to see on which of these queues these operations are being executed. The GPU obviously doesn't care on which CPU thread the command buffer was generated on.

To me, it seems like the VkCtxScope constructor could just take an additional VkQueue handle and instead of writing the id of the current thread, we could write the queue handle. However, I'm not sure how Tracy internally handles the grouping of timelines so I don't know where to begin to make changes to support this. I'd also like to hear what other people think and if, perhaps, this functionality already exists but I just don't know about it.
