[camera] Camera with MediaSettings: platform implementations (federat…

…ed) (flutter#5223)

## Platform implementations of federated plugin

This is the `platform implementations` part of `camera` PR flutter#3586.

`camera_platform_interface: 2.6.0` merged and published in PR flutter#3615.

Now repeating steps 3,4 (see [Changing federated plugins](https://github.com/flutter/flutter/wiki/Contributing-to-Plugins-and-Packages#changing-federated-plugins)), because `camera/camera` depends on implementations `camera/camera_android`, `camera/camera_web` etc.
