Li Hao	7abcadfce6	Add toggle to disable the tick->ns conversion of timestamp query ... Although the error rate of timestamp tick->ns conversion is very small (3e-5), some profiling scenarios, such as CPU/GPU timestamp calibration on Windows, require absolutely accurate timestamps. Add new toggle to resolve timestamps to ticks for those cases where zero error is required. Add an end2end test for GPU timestamp calibration on D3D12 backend. Disable timestamp period calculation on Device when the DisableTimestampQueryConversion is enabled.
