[VM/Timeline] Make timestamp1_or_id variables more understandable

This CL improves documentation, and renames fields/methods to make it
more understandable that timestamp1 and id are stored in the same field
of dart::TimelineEvent (because the event types that need to store
timestamp1 are disjoint from the ones that need to store id).

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.

Dart

A client-optimized language for fast apps on any platform

Dart is:

  • Optimized for UI: Develop with a programming language specialized around the needs of user interface creation.

  • Productive: Make changes iteratively: use hot reload to see the result instantly in your running app.

  • Fast on all platforms: Compile to ARM & x64 machine code for mobile, desktop, and backend. Or compile to JavaScript for the web.

Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:

  • Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.

  • Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
