Add a method to IServiceCollection, for Razor, to add a consent handler

[bakerCaleb]

Is your feature request related to a problem? Please describe.
When writing a Razor web app, I'd like to add a consent handler. There is no available method. I'm using the one for Blazor, which I think will work, but it is confusing and I'm not confident it is the correct approach.

Example from ConfigureServices() in Startup.cs:

services.AddServerSideBlazor()
.AddMicrosoftIdentityConsentHandler();

Describe the solution you'd like
I'd like something like:
services.AddServerSideRazor()
.AddMicrosoftIdentityConsentHandler();

Describe alternatives you've considered
If it's the same code for Razor and Blazor, maybe just make it neutral, like:

services.AddServerSide()
.AddMicrosoftIdentityConsentHandler();

Additional context
Add any other context or screenshots about the feature request here.

The AddMicrosoftIdentityConsentHandler does not use the IServerSideBlazorBuilder

microsoft-identity-web/src/Microsoft.Identity.Web/MicrosoftIdentityCircuitHandler.cs

Lines 31 to 43 in 1a073ed

	public static IServerSideBlazorBuilder AddMicrosoftIdentityConsentHandler(
	this IServerSideBlazorBuilder builder)
	{
	if (builder == null)
	{
	throw new ArgumentNullException(nameof(builder));
	}
	builder.Services.TryAddEnumerable(ServiceDescriptor.Scoped<CircuitHandler, MicrosoftIdentityServiceHandler>());
	builder.Services.TryAddScoped<MicrosoftIdentityConsentAndConditionalAccessHandler>();
	return builder;
	}
	}

Lets add an overrides that takes an IServiceCollection and returns it
