Add none generic service middleware registration methods in Autofac

These changes introduce new methods to register service middleware in the Autofac library. Also, a new test has been added to Autofac.Specification.Test to ensure that the middleware is getting invoked correctly when a service is registered. These methods allow for more precise control of the pipeline during the resolve request process.
