Srujan Gaddam e253aeff60 Remove package:js references and move to dart:js_interop (flutter/engine#41212)
dart:js_interop and package:js will start conflicting. Eventually, we
want people to only use dart:js_interop, so this CL refactors code to do
that.

Unblocks https://dart-review.googlesource.com/c/sdk/+/294130/8 and
prevents confusing shadowing of dart:js_interop annotations like we do
today.
