Several changes for timestamp bundle:

Browse Source 
Fully defined the structure.
Single copy of it + single timer across all modules, managing it is now the responsibility of KernelState.

add global_critical_region::PrepareToAcquire, which uses Prefetchw on the global crit. We now know we can use Prefetchw on all cpus that have AVX.
add  KeQueryInterruptTime, which is used by some dashboards.

add threading::NanoSleep
