Add a Mentions room list filter (#5885)

* Add a Mentions room list filter

Adds a new filter chip to the room list that shows only rooms with
unread mentions, using the new mentions room list filter from the
Rust SDK (matrix-org/matrix-rust-sdk branch matthew/mentions-filter).

The SDK version needs bumping to a release that includes the new
filter kind before this can build against the released components.

* Order the room list filters by expected usage

Move Favourites ahead of People and Rooms so the more commonly used
filters (Unreads, Mentions, Favourites) sit first in the chip row —
Rooms and Invites are used rarely enough that it's fine for them to
wrap off the side.

* update the SDK and use the appropriate rust filter types

* preview tests + app settings flag for mentions
