Use xplat webview control for Audible login

- Use Avalonia-based webview control for Audible login with Chardonnay
- Remove webview interfaces from IInteropFunctions
- Remove Microsoft.Web.WebView2 package from WindowsConfigApp
- Add Microsoft.Web.WebView2 to LibationWinForms
- Remove all other login forms except the external login dialog (fallback in case webview doesn't work). The AudibleApi login with username/password doesn't work anymore. Need to use external browser login method.
