[ Service / DDS ] Advertise DDS as the VM service, bump version to 4.0

This change does the following:
  - The DDS URI will be reported by the VM as the VM service URI. If DDS
    disconnects, the VM service URI will be reported instead. This only
    impacts the standalone VM.
  - Updated the service protocol to 4.0 and removed the following
    deprecated functionality:
      - Client synchronization RPCs (these now live in DDS)
      - getWebSocketTarget (no longer needed as the VM service no longer
        tries to redirect web socket clients to DDS)
  - Regenerates package:vm_service based on the new spec, prepare for
    5.0 release

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).
