[Blazor Wasm Auth] Single httpclient for both authenticated and non authenticated users

### Is your feature request related to a problem? Please describe.
I do not think it is necessary to have separate http clients for authenticated and non authenticated users (see https://docs.microsoft.com/en-us/aspnet/core/blazor/security/webassembly/additional-scenarios?view=aspnetcore-5.0). The developer has to create a lot of additional code, especially for typed clients.

### Describe the solution you'd like
Before sending the request can we check to see if the user is authenticated or not and determine whether to apply the handler logic.

Here is a hack to get this working with the current AuthorizationMessageHandler

public class ApiAuthorizationHandler : AuthorizationMessageHandler
{
private readonly NavigationManager navigation;
private readonly IConfiguration config;
private readonly AuthenticationStateProvider authStateProvider;

//https://github.com/dotnet/aspnetcore/blob/master/src/Components/WebAssembly/WebAssembly.Authentication/src/Services/AuthorizationMessageHandler.cs
public ApiAuthorizationHandler(IAccessTokenProvider provider,
NavigationManager navigation,
IConfiguration config,
AuthenticationStateProvider authStateProvider) : base(provider, navigation)
{
this.navigation = navigation;
this.config = config;
this.authStateProvider = authStateProvider;
}

protected override async Task SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)
{
//Hack to bypass handler already configured exception
var field = this.GetType().BaseType.GetField("_authorizedUris", BindingFlags.Instance | BindingFlags.NonPublic);
field.SetValue(this, null);

var authState = await authStateProvider.GetAuthenticationStateAsync();

if (authState.User.Identity.IsAuthenticated)
{
ConfigureHandler(new[]{config.GetValue("ServerUri")});
}
else
{
//Satisfy validation so that we can call api without needing to be logged in
ConfigureHandler(new[]{navigation.BaseUri});
}

return await base.SendAsync(request, cancellationToken);
}
}`
