New Architecture (non-UWP) support for Windows

[ericfle]

I've noticed the project still have UWP references at https://github.com/react-native-webview/react-native-webview/blob/master/windows/ReactNativeWebView/ReactNativeWebView.vcxproj and I assume it's still blocking the support for new architecture where the windows apps are moved from UWP to WinAppSDK (ref: https://microsoft.github.io/react-native-windows/docs/new-architecture). Is that something already in progress or at least tracked in some task?
