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.
