What does this PR do?
This PR improves the handling of multi-GPU passes in the GPU Profiler -> TimestampView.
It does the following:
One remaining issue is that multiple timelines are drawn and scaled independently at the moment.
Since there currently is no way to match/synchronize timestamps between devices, each GPU scales its own timeline to the full length of the window, instead of scaling all passes the same and shifting them along as needed.
This would require something like calibrated timestamps to handle better.
In the meantime, timelines are internally consistent but cannot be directly compared with one another.
How was this PR tested?
Tested with the MultiGPU RPI sample in ASV.
