tools: acrntrace: output trace data as raw data

Browse Source 
Benefits of outputing trace data as raw data:
  - Smaller trace data size
  - More convenient to add new trace entry. There is no need to change acrntrace
    when we add new trace entry to HV. All we need do is to update the analysis
    scripts to deal with this situation.

Trace data size(with 1 UOS):
~57M   -- with patch
~137M  -- without patch
