[dart:html] Remove casts in cancel() method

Casts in _EventStreamSubscription.cancel() are causing unwanted failures
in ddc when we turn weak null safety warnings into errors via a flag. By
removing the casts more apps can run when the weak mode errors are
enabled. The null value is used inside the SDK to signal synchronous
behavior.

This is a temporary fix until we can resolve the larger issue with the
API in dart:html. See https://github.com/dart-lang/sdk/issues/44157.

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).
