Patchset 1 is a reland of commit
f52bdb96aa, and Patchset 2 adds a
corrected reland of commit 0d0e301979.
The leak in g3 was caused by moving the `state_ = 0;` line before the
`owns_label()` check in `TimelineEvent::Reset`.
TEST=Ran the g3 tests that were failing on a cbuild copy with these
changes (sponge2/1134a5bb-5168-4e4c-bb03-72a7d7ad6ab4).

This is a reland of commit 46e70a7c07
It turns out that flow events do need to be associated with IDs in
Chrome's trace format, so the diff between patchset 1 and 6 contains the
changes required to document that.
TEST=Checked that duration events still looked correct in traces written
by the Perfetto file recorder. Checked that events still looked correct
in traces recorded to the MacOS recorder. Checked that flow events still
looked correct in Observatory. Ran the
vm/cc/DartAPI_TimelineEvents_Serialization test in debug mode, and with

The only user of this API is no longer using it (see cl/519087228).
It's possible we'd re-introduce such an API in the future,
in which case we may want to:
- make it more clear what the GC times mean (are concurrent threads for
mark/sweep or parallel threads for paralell marking included,
is time in wallclock or cpu time, ...)
- include information more useful for users, such as maximum
synchronous pause times

Turns out, even thought Heap constructs an elaborate event
object, and attaches it to the ServiceEvent, the service
does its own event construction (again).
As a result the ServiceEvent has quite a different layout
and no concept of before/after.
This CL changes Dart_GCEvent to more closely follow the
JSON event emitted by Service.

Moved the responsibility to provide MaxRSS and CurrentRSS from the VM to
the embedder.
The embedder can opt-it by setting a Dart_GetEmbedderInformation
callback using the public Dart_SetEmbedderInformationCallback API.
The implementation of the Dart_GetEmbedderInformation should mandatory
fill the version field and the ones it is able to fill.
The name field must reference a constant C style string, it will not be
freed by the VM code.
