[Suggestion] Use `Symbol.dispose` to replace our own `Disposable`

How can Tango be improved?

The Explicit resource management proposal adds primitives for disposable pattern.

However, using it requires a polyfill as browser support is not good now.

Symbol.dispose and Symbol.asyncDispose can be easily polyfilled, but not for DisposableStack. I also don't like https://github.com/es-shims/DisposableStack, I don't need a ES3 compatible polyfill with millions of dependencies.

How should the API change?

Add our own polyfills, and refactor disposables to use those primitives.
