Add AuthorizationBuilder

[HaoK]

AuthZ part of #42235

I didn't update everything, but updated enough of the tests to feel confident that this does reduce lines of code even just in our tests, and that the basics are working, will finish the rest of this assuming this is something that we want to take for real.

Before

      var authorizationService = BuildAuthorizationService(services =>
        {
            services.AddAuthorization(options =>
            {
                options.AddPolicy("Basic", policy => policy.RequireClaim("Permission", "CanViewPage"));
            });
        });

After

            services.AddAuthorization().AddPolicy("Basic", policy => policy.RequireClaim("Permission", "CanViewPage")));```

Note: this does change the return value for AddAuthorization* methods to return the new AuthorizationBuilderServiceCollection that wraps the service collection

Yeah I like this approach that enables us to return the builder from
builder.Authorization and services.AddAuthorization() (mostly) without a breaking change.

Updated with new proposed AddAuthorizationBuilder name

@DamianEdwards is this something you want me to get in for preview6, or can this wait for preview7? The PR Is basically ready, since I don't have to update all tests to use the new API

[DamianEdwards]

It would still need an API review and we should likely do this change at the same time as introducing the new WebApplicationBuilder.Authorization property. Code complete is tomorrow and we still have quite a lot in preview.6 to land in an SDK build so might be wise to push this to preview.7

[HaoK]

@captainsafia do you want to make the WAB.Authorization side of things in my branch or do you want me to do it (for preview 7)?

[davidfowl]

Lets put this up for API review (write an API proposal based on this PR in the issue)

[davidfowl]

Set* seems better tbh

[HaoK]

Okay, going back to the original SetInvokeHandlersAfterFailure
