[dartdevc] Fix violations of library_prefix lint

Rename the library prefix used in imports from `JS` to `js_ast`. Create more of
a distinction between:
* `JS` the library.  Now named `js_ast`.
* `js` the const instance of a JSBuilder.
* `JS` the helper to inline javascript in the SDK patches
  and runtime libraries.

Ignore the lint in the js_ast directory to avoid additional diffs for the
eventual un-forking of the package.

Cleanup a few unused imports.

Issue #37218

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 has 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).
