Align Roctracer to TSC Clock

[sraikund16]

Summary: Right now we align Roctracer events to system clock blindly regardless of what we are using in torch.profiler. We should use a clock based on what is defined instead. This wont fix overlapping kernel events since we do a static offset when aligning but it will help make sure that kernel events always happen after kernel launches
