Align traceStart argument order

This change updates PerfettoUtils.traceStart()'s argument order to align
with the order of arguments in its only caller, TraceUtils.traceStart().
This is intended to avoid possible confusion when adding parameters in
the future.

Test: Check that the Perfetto config used when capturing a trace using
      long traces / bug report attachment are still correct.
