  Disable timestamp call from AddTraceEvent for Android platform
  
  Android platform's addTraceEvent ignores the timestamp arg, so there is
  no reason to make this call (and it shows as the hotspot).
  Behind a new define to avoid breaking this in Chromium Android builds
  where the timestamp is actually used.
