[Blazor] First class integration with HttpClientFactory

[javiercn]

The other major challenge here is with regards to how AuthenticationService interoperates with other parts of the user app, like scoped services in their own "sub-scope". This is relevant when users are leveraging things like Entity Framework for which we recommend using owning component scope as well as other libraries like HttpClientFactory that create their own scopes. In these cases, users are not able to access the current authenticated user within those services or any information associated with the circuit. The challenge here involves "being able" to have a "per circuit" scope that flows to any "nested scope".

We hope to investigate this in the .NET 10 timeframe and make a preview package available, but we don't expect this land in a stable form for .NET 10.
