Support debugging client-side Blazor from VS

Is there a technical roadblock to this approach?

1. Setup Visual Studio for remote debugging.
2. Connect to the mono WASM runtime engine in the browser.
3. Get all of the VS debugging capabilities "for free".

You'd need to use the browser debugger for debugging DOM, styles, etc., but everything else would be through Visual Studio.

@ejhewy It's extremely nontrivial but we are working on it (well, mostly the Mono team are). We don't get "all of the VS debugging capabilities for free" because each capability involves detailed work to make the runtime support and present in a form that the IDE can understand.
