[beta][dart2wasm] Use node's enclosing library annotation for lowerings

Closes https://github.com/dart-lang/sdk/issues/55359

The current library's annotation is used for the interop lowerings
in dart2wasm. For most members, this is okay because we emit the
equivalent JS code for the member when we visit the procedure and
not when we visit the invocation. However, for methods, the invocation
determines the resulting JS call due to the existence of optional
parameters. In that case, if the invocation was not in the same
library as the interop member declaration, it results in using the
wrong library's annotation value.

Adds tests for this case and does some cleanup of existing tests.

Specifically:
- Adds a consistent naming scheme for test libraries that are
namespaced.
- Adds code to delete the non-namespaced declarations so that the
namespaced interop methods don't accidentally call those declarations.
- Removes differentArgsMethod which was already tested in
js_default_test.
- Removes use of js_util in favor of js_interop_unsafe.

Dart

An approachable, portable, and productive language for high-quality apps on any platform

Dart is:

  • Approachable: Develop with a strongly typed programming language that is consistent, concise, and offers modern language features like null safety and patterns.

  • Portable: Compile to ARM, x64, or RISC-V machine code for mobile, desktop, and backend. Compile to JavaScript or WebAssembly for the web.

  • Productive: Make changes iteratively: use hot reload to see the result instantly in your running app. Diagnose app issues using DevTools.

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).
