Space filters (#4977)

* Add support for SpaceFilters on the SpaceServiceProxy level and a screen that renders them

* Add aliases to a couple of space room mocks

* Update translations and related snapshots

* Add a feature flag for space filters

* Add a new room summary provider filter that takes a list of room identifiers next to the normal state filters

This will take the SpaceFilter's descendants and combine it with the normal filters to reduce the rooms shown

* Add a new space filter button to the home screen and link it to the SpaceFiltersScreen and the actual RoomSummaryProvider room list filters

* Bump the RustSDK to v26.01.20-2 for SpaceFilter support.

* Add a cancellation button to the space filters screen

* Make the filter presentation mode liquidy, move the sheet to within the home screen.

* Address PR comments
