RoomScreenViewModel is now TimelineViewModel

[Velin92]

The first step into separating the timeline behaviour from the generic room behaviour.

For now this is mostly a renaming, and some small signature and function changes (for example the draft is now handled directly by exposed functions from the composer through the coordinator).

The TimelineViewModel still does all the room screen work, but I created a view model and some models for it, in case we want to slowly migrate over time some functionalities from the TimelineViewModel into the new RoomScreenViewModel. ( For example the pinned banner handling could be migrated to it or the navigation to the details... and so on...)

I also added the TimelineViewModel to the PinnedEventsTimelineCoordinator, and is now possible to see the pinned events, even if actions are not yet handled and there are some errors being thrown by pagination
