Room list: avoid excessive re-renders on room list store update or filter change (#32663) ...

* perf(room list): clear room list item vm only when changing space

Clearing all the item vms at every room list change is causing massive
re-render of all the room list items. References to the vms are already
removed when out of view (see RoomListViewMode.updateVisibleRooms) and
handled by GC.

* perf(room list): avoid to re-render filters at every room list update

RoomListView re-renders on update but the filters (children) don't need
to.

Add a memo to avoid excessive-rerenders.

* chore: add `keepIfSame` to do diff on vm objects

* perf(room list): avoid to create new filter ids and keys when the room list is updated

The filterKeys are passed in the virtuoso context so it should reduce
internal computing

The filter ids array has always the same value, there is no point to
create a new instance.

* test(room list): remove no longer relevant test

* test(room list): add new test to ensure that room list item vms are preserved
