Srujan Gaddam 18b7dd771b Reland "[dart:js_interop] Remove Object.toJS and JSNumber.toDart"
This is a reland of commit 16fcfe7eae

Original change's description:
> [dart:js_interop] Remove Object.toJS and JSNumber.toDart
>
> Modifies JSBoxedDartObject reified type on JS backends and also
> modifies JSBoxedDartObject.toDart now that a proper box is introduced.
> Also uses a JS symbol in JSBoxedDartObject.toDart for a property
> check so that different Dart apps don't accidentally share Dart
> objects. It's now an error to call this function on non-boxed objects.
>
> Fixes a type issue where creating a new object literal with the JS
> foreign function was resulting in dart2js thinking toJSBox would
> always throw. Changing the typeDescription to PlainJavaScriptObject
> instead of =Object fixes that issue.
>
> CoreLibraryReviewExempt: Backend-specific library.

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).
