Add basic support for HomeWizard v2 API configuration flow

[DCSBL]

Proposed change

This API allows the user to configure the device via the v2 API. This API is now using a authorization step similar to Hue, where the user has to proof the possession by pressing the button on the device. Therefore the config flow has to be adjusted.

To keep this PR a bit concise, I didn't implement reauthorization, extensive error handling and migration. This will be done in follow-up PR's if that is okay.

Documentation update is WIP.

You can test this with real hardware, ask me via a DM on discord for instructions.

Waits for #135315
