Towards https://github.com/flutter/flutter/issues/134501.
This change is based on https://github.com/flutter/engine/pull/48090. It changes the `RenderView` to be dynamically sized based on its content if the `FlutterView` it is configured with allows it (i.e. the `FlutterView` has loose `FlutterView.physicalConstraints`). For that, it uses those `physicalConstraints` as input to the layout algorithm by passing them on to its child (after translating them to logical constraints via the device pixel ratio). The resulting `Size` that the `RenderView` would like to be is then communicated back to the engine by passing it to the `FlutterView.render` call.
Tests will fail until https://github.com/flutter/engine/pull/48090 has rolled into the framework.

These properties have reached the end of their deprecation period.
* Adds `TestDisplay`
* Updates `TestPlatformDispatcher` to wrap all `Display`s and relate them to their appropriate `TestFlutterView`
* Updates `TestFlutterView` to tie `devicePixelRatio` to its display as per the documentation on `Display`
