**This option is not recommended as it completely obliterates all chances of being able to support someone with a broken room list. It is intended for specific testing scenarios only.**
Previously we were creating a notification state whenever we needed one, which was leading to hundreds of listeners even on a small account. To ease the burden, and reduce the load of having to wake so many listeners, we now record a single listener for each tag ID and room combination.
This commit also introduces a number of utilities to make future notification work a bit of an easier transition, such as the `isX` and `hasX` getters on the new NotificationState abstract class. Similarly, "snapshots" have been added to reduce code duplication between different kinds of states checking for updates.
The ListNotificationState is now heavily tied into the store which offers it to help reuse the cache of room notification states.

This is more general maintenance than performance as the RoomList doesn't need to be generating layouts for the sublists, and it certainly doesn't need to be creating a bunch of extra ones.
The sublists are perfectly capable of getting their own layout instance and using it, and we are perfectly able to limit the number of these things we create through the session's lifespan.
We have to trigger an initial render because during the login process the user will have started syncing (causing lists to generate) but the RoomList component won't be mounted & listening and therefore won't receive the initial lists. By generating them on mount, we ensure that the lists are present once the user gets through the login process.

Disclaimer: this is all of the horrible because it's not meant to be here. Invites in general are likely to move out of the room list, which means this is temporary. Additionally, the communities rework will take care of this more correctly. For now, we support the absolute bare minimum to have them shown.
This also passes the tagId to the sublist so it doesn't have to rip it out of the `layout`. It doesn't get a layout until later anyways, which causes some null issues.
This is a work in progress, but covers the coarse areas. This uses all-new classes to better describe what everything is, and to reduce the number of selectors we keep track of.
This is primarily layout for the list and not actually the final structure. For example, some buttons are missing and other areas are not styled correctly - the idea in this commit was to get things roughly in the right place and work on it.

This is an incomplete implementation and is mostly dumped in this state for review purposes. The remainder of the features/bugs are expected to be in more bite-sized chunks.
This exposes the RoomListStore on the window for easy access to things like the new filter functions (used in debugging).
This also adds initial handling of "new rooms" to the client, though the support is poor.
Known bugs:
* [ ] Regenerates the entire room list when a new room is seen.
* [ ] Doesn't handle 2+ filters at the same time very well (see gif. will need a priority/ordering of some sort).
* [ ] Doesn't handle room order changes within a tag yet, despite the docs implying it does.
This is to get around the problem of a slow dispatch loop. Instead of slowing the whole app down to deal with room lists, we'll just raise events to say we're ready.
Based upon the EventEmitter class.
This does a number of things (sorry):
* Estimates the type changes needed to the dispatcher (later to be replaced by https://github.com/matrix-org/matrix-react-sdk/pull/4593)
* Sets up the stack for a whole new room list store, and later components for usage.
* Create a proxy class to ensure the app still functions as expected when the various stores are enabled/disabled
* Demonstrates a possible structure for algorithms
