[desktop] Include generated native windows notifs

Summary:
This module was generated with NodeRT which generates native node modules from Windows API definitions. It doesn't build yet, changes required for it to work will be included in the later diff. The module is ignored for now in the monorepo and isn't built when running yarn commands.

It was generated using the UI version of the NodeRT:

• winMD file was Microsoft.WindowsAppSDK.1.2.221109.1/lib/uap10.0/Microsoft.Windows.PushNotifications.winmd, where Microsoft.WindowsAppSdk.1.2.21109.1 is a nuget package
• in namespaces I selected microsoft.windows.notification
• I unselected generate "Generate TypeScript" and "Build module"

Test Plan: Check if it doesn't break yarn install
