UWP to WinUI

[PaymonK]

The native Windows runner of Zebble is a very useful tool for development and debugging using Visual Studio.

With UWP being deprecated by Microsoft we need to migrate to WinUI.

• Update the Zebble source
• Update the Zebble plugins
• Create a step-by-step guide for migrating existing Zebble apps

I can move to WinUI if you want
Microsoft just recently published WindowsAppSDK V1.0 which contains the stable WinUI.

WinUI in Windows App SDK offers good performance (but lacks some UWP features) and it's being consistently updated.
Look at my benchmark:

and look compare it with a previous version:

Also Xamarin Classic will be deprecated and Microsoft is bringing .NET 6 for Xamarin.

We could migrate them altogether
