Use chromium trace_event implementation in blink
Previously blink's trace_event was implemented in the way to make
blink a standalone library:
TRACE_EVENT macros
-> TRACE_EVENT internal macros
-> EventTracer
-> Chromium's trace event C++ API
Now blink is no longer a standalone library, so we can use chromium's
trace_event macros directly.
This CL
- removes blink's trace_event implementation
- lets blink's TraceEvent.h include chromium's trace_event.h,
- lets blink's TracedValue implement ConvertableToTraceFormat,
- keeps support of blink CString type as trace values.
