Support Request, Response and User for minimal actions (dotnet#33883)

Adds support to minimal actions for parameters of type HttpRequest,
HttpResponse, and ClaimsPrincipal to be bound to the values of the
Request, Response and User properties of the HttpContext respectively.

Also cleans up some typos in the RequestDelegateFactory tests.

Addresses dotnet#33870.
