Build with Visual Studio 2022 (#1793)

- Use Visual Studio 2022
- Use an Azure Pipelines image which has Visual Studio 2022 installed
- Use the v143 C++ build tools
- Use the Windows SDK version 22000
- Raise the minimum platform version to 17763
  - As a consequence of this change, we will use the "msix" file extension instead of "appx" for our packages
- Update UI tests from .NET Core 2.1 to .NET Core 3.1
