Derek Xu afa3594ca1 [VM/Timeline] Support flow events in the Perfetto file recorder
This supports flow events reported through dart:developer, but does not
support ones reported with Dart_TimelineEvent in dart_tools_api.h. That
will have to be supported in a future CL.

TEST=CI, manually verifying that flow arrows appeared on flow events in
the trace viewer for traces recorded with our Perfetto recorder
