Make sure .NET WebAssembly runtime features are properly documented

[danroth27]

We have a bunch of great content in https://github.com/dotnet/runtime/blob/main/src/mono/wasm/features.md about various features of the .NET WebAssembly runtime. We should make sure the relevant user facing features from this doc are covered in our official docs on Microsoft Learn, so they are discoverable, appropriately localized, etc.

This issue tracks going through the features.md doc and creating issues in the dotnet/aspnetcore.docs for any official doc content that should be added.

Let me know if you'd like me to create a "Runtime" node of articles in the ASP.NET Core Blazor doc set, holding articles created from the features.md article or pointing to existing Learn-hosted content. A single issue over there could be set up to resolve it.
