We always had an associated document for the spec defined timelines (i.e. `DocumentTimeline` and `ScrollTimeline`) but not for the ad-hoc `InternalAnimationTimeline` so lets store one for that as well and use a `Ref` instead of a `Ptr`. This requires `convert_a_timeline_time_to_an_origin_relative_time` to be implemented for `InternalAnimationTimeline` since it can now be called where it previously wasn't due to the absence of a document - we just return an empty optional since it's not used anywhere.

// Note: Due to the hierarchical nature of the timing model, updating the current time of a timeline also involves:
|
|
// - Updating the current time of any animations associated with the timeline.
|
|
// - Running the update an animation's finished state procedure for any animations whose current time has been
|
|
// updated.
|

// - Queueing animation events for any such animations.

// NB: This mirrors what the event loop does for DocumentTimeline in Document::update_animations_and_send_events().
