[web] Use new APIs from dart:ui_web (#4168)

The following APIs are now exposed through `dart:ui_web` which eliminates the need for shims:
- `platformViewRegistry`
- `webOnlyAssetManager`
- `urlStrategy`

## Issues

* Fixes https://github.com/flutter/flutter/issues/55000

## Minimal `stable` version

THIS PR CANNOT LAND UNTIL THE NEW `dart:ui_web` APIS MAKE IT INTO A STABLE FLUTTER RELEASE.

* Needs 5a7ab5a147
