Rename DOM types and change namespace

Fixes: #12553 This change renames all of our browser/DOM specific types from `UIFooEventArgs` to `FooEventArgs` and puts the in the `.Web` namespace. In addition to this, we're moving `EventHandlers` and `BindAttributes` to the same. This has the impact of scoping the mappings those classes provide based on the `.Web` namespace. This means that we now expect `.Web` to be present as a using in basically all contexts for a browser-based Blazor app. Updated templates, samples and tests. I'll also need to update about a million tests in the compiler codebase. I've logged https://github.com/aspnet/AspNetCore.Docs/issues/13832 to track the docs and release notes part of this work.
