[bug] Local camera track rotation when connecting to the Room

[DominikNozka]

When you connect to the room on iOS device with Flutter SDK camera is initially rotated by 90 degrees. After a couple of seconds it goes back to portrait mode automatically. In some cases camera does not go back to portrait mode.

Steps to reproduce the behavior:

Connect to the room like this with physical iOS device.

room = Room(
      roomOptions: RoomOptions(
        adaptiveStream: true,
        dynacast: true,
        e2eeOptions: e2eeOptions,
      ),
    );`

    final listener = _room.createListener();
    await _room.prepareConnection(url, token);
    await _room.connect(
      url,
      token,
    );

Possible solution
Local video track does not rotate when I use FastConnectOptions for Room object creation.

in our case, it does not happen on a deterministic manner, sometimes happens sometimes it doesn't or even local video track is squared

This seems to be related to PlatformView, please refer to this line https://github.com/livekit/client-sdk-flutter/blob/main/example/lib/widgets/participant.dart#L146
and set to VideoRenderMode.texture to solve the rendering issue
