Change adapts the `base_capturer_pipewire` so that a portal can be injected in the capturer. This allows the remoting to inject its own portal for the purpose of capturing desktop stream as long as the injected portal provides implementation of the new interface that is added as part of this change. Additionally, a method has been exposed on the capturer to get details about the portal session so that the remoting implementation can use the same underlying session for controlling inputs on the remote host. Finally, desktop capturer interface is extended with a generic method `GetMetadata` that is used to retrieve session related information by CRD and relay it over to its input injector. Clients provide override for the method and it eventually invokes the underlying `GetSessionDetails` method on the portal instance.
