[windows] Account for ObjectDisposedException coming from device tests for MauiWebView

[PureWeen]

Description

After reviewing some crash dumps for WinUI we noticed an ObjectDisposedException

Currently we haven't found a way to detect for this beyond just catching and logging the exception.

I also wonder if we need the internal web view on this code and if that's complicated matters even more. That internal WebView was added 8 years ago for WinRT

xamarin/Xamarin.Forms#277

I started a branch here
https://github.com/dotnet/maui/tree/catch_disposed_exception

With a somewhat naive approach to just catch the exception for now and log it

But I'm curious if

1. we can just remove that internal webview for simplifying purposes
2. find a better solution then just catching the disposed exception
