In https://github.com/lightpanda-io/browser/pull/1774 we started to track Ranges in the page in order to correctly make them "live". But, without correct lifetime, they would continue to be "live" even if out of scope in JS. This commit adds finalizers to Range via reference counting similar to Events. It _is_ possible for a Range to outlive its page, so we can't just remove the range from the Page's _live_range list - the page might not be valid. This commit gives every page an unique id and the ability to try and get the page by id from the session. By capturing the page_id at creation-time, a Range can defensively remove itself from the page's list. If the page is already gone, then there's no need to do anything.
