Restabilize room list ordering with prefiltering on spaces/communities 

Fixes https://github.com/vector-im/element-web/issues/16799

This change replaces the "relative priority" system for filters with a kind model. The kind is used to differentiate and optimize when/where a filter condition is applied, resulting in a more stable ordering of the room list. The included documentation describes what this means in detail.

This also introduces a way to inhibit updates being emitted from the Algorithm class given what we're doing to the poor thing will cause it to do a bunch of recalculation. Inhibiting the update and implicitly applying it (as part of our updateFn.mark()/trigger steps) results in much better performance.

This has been tested on my own account with both communities and spaces of varying complexity: it feels faster, though the measurements appear to be within an error tolerance of each other (read: there's no performance impact of this).

An exception for the sticky room placement is when there's suddenly not enough rooms to maintain the placement
exactly. This typically happens if the user selects a room and leaves enough rooms where it cannot maintain
the N required rooms above the sticky room. In this case, the sticky room will simply decrease N as needed.

The store is responsible for the ordering, upkeep, and tracking of all rooms. The room list component simply gets
an object containing the tags it needs to worry about and the rooms within. The room list component will
decide which tags need rendering (as it commonly filters out empty tags in most cases), and will deal with
all kinds of filtering.
## Filtering
Filters are provided to the store as condition classes, which are then passed along to the algorithm
implementations. The implementations then get to decide how to actually filter the rooms, however in
practice the base `Algorithm` class deals with the filtering in a more optimized/generic way.
Filters are provided to the store as condition classes and have two major kinds: Prefilters and Runtime.
The results of filters get cached to avoid needlessly iterating over potentially thousands of rooms,
as the old room list store does. When a filter condition changes, it emits an update which (in this
case) the `Algorithm` class will pick up and act accordingly. Typically, this also means filtering a
Prefilters flush out rooms which shouldn't appear to the algorithm implementations. Typically this is
due to some higher order room list filtering (such as spaces or tags) deliberately exposing a subset of
rooms to the user. The algorithm implementations will not see a room being prefiltered out.
Runtime filters are used for more dynamic filtering, such as the user filtering by room name. These
filters are passed along to the algorithm implementations where those implementations decide how and
when to apply the filter. In practice, the base `Algorithm` class ends up doing the heavy lifting for
optimization reasons.
The results of runtime filters get cached to avoid needlessly iterating over potentially thousands of
rooms, as the old room list store does. When a filter condition changes, it emits an update which (in this
case) the `Algorithm` class will pick up and act accordingly. Typically, this also means filtering a
minor subset where possible to avoid over-iterating rooms.
All filter conditions are considered "stable" by the consumers, meaning that the consumer does not
expect a change in the condition unless the condition says it has changed. This is intentional to
maintain the caching behaviour described above.
One might ask why we don't just use prefilter conditions for everything, and the answer is one of slight
subtly: in the cases of prefilters we are knowingly exposing the user to a workspace-style UX where
room notifications are self-contained within that workspace. Runtime filters tend to not want to affect
visible notification counts (as it doesn't want the room header to suddenly be confusing to the user as
they type), and occasionally UX like "found 2/12 rooms" is desirable. If prefiltering were used instead,
the notification counts would vary while the user was typing and "found 2/12" UX would not be possible.
## Class breakdowns
The `RoomListStore` is the major coordinator of various algorithm implementations, which take care
of the various `ListAlgorithm` and `SortingAlgorithm` options. The `Algorithm` class is responsible
for figuring out which tags get which rooms, as Matrix specifies them as a reverse map: tags get
defined on rooms and are not defined as a collection of rooms (unlike how they are presented to the
user). Various list-specific utilities are also included, though they are expected to move somewhere
more general when needed. For example, the `membership` utilities could easily be moved elsewhere

The various bits throughout the room list store should also have jsdoc of some kind to help describe
