Mouad Debbar e2e1b979c4 [web] Make devicePixelRatio ready for multi-view (flutter/engine#44783) ...

This PR moves the source of truth for`devicePixelRatio` to the `EngineFlutterDisplay` singleton.

Main things that this PR is trying to do:
- `EngineFlutterDisplay` is a singleton that represents information about the display.
  - The `devicePixelRatio` can be overriden in tests.
  - The `browserDevicePixelRatio` gets the value directly from the browser and can't be overriden.
- Remove `EngineSingletonFlutterWindow` and incorporate it into `EngineFlutterWindow`.
