Minor fixes to tracing

The chrome://tracing expects the timestamp to be in microseconds, but
it had been stored in the TraceItem in nanoseconds, so this fixes it.

Also adds quotes around the thread_id, since on Mac it is written in hex
format and so the JSON parser doesn't recognize it.

Finally, adds toolchain information to the import traces.
