Simplify Windows setup

[TekExplorer]

I'm considering using this package for desktop webviews, but the Windows setup concerns me.

No other such package that i'm aware of requires initialization in the main runner.

By my understanding, you should be setting up a normal method channel and providing a static method in dart that we can use to initialize it ourselves.

webview_windows has no manual configuration needed.

this is one of the only webview packages i've seen so far that does linux

Please explain.
