[dart2js, ddc] Add preamble to seal Object prototype

- Add a new dart2js preamble file that seals the native object prototype.
- Use the file when running DDC in d8 locally.

Once this change lands the new preamble can be used in the script that
runs d8 on the benchmarking bots.

If benchmark results look good, I will followup with a change to enable
the prototype sealing in SDK test configurations as well.

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).
