Recording timing info in trace events when D3D12 queue submit

Add a toggle RecordDetailedTimingInTraceEvents. When this toggle is
enabled, record detailed timing information in trace events right
before calling ExecuteCommandLists on a D3D12 command queue, and the
information includes system time, CPU timestamp, GPU timestamp, and
their frequency.
