[windcentrale] Adapt binding to new API (#14770)

* [windcentrale] Adapt binding to new API

Reworks the binding so it can be used with the new API that also requires authentication.

Also adds the following:

* Account things to provide authentication details
* Implementation for getting and refreshing tokens using AWS Cognito
* Windmill discovery based on the participations in projects
* Properties with additional data for windmills like turbine type, build year, location coordinates
* Adds support for "Het Vliegend Hert" windmill
* Unit tests for JSON (de)serialization

Fixes #13625
