Sliding sync: don't fetch room summary for named rooms. (#17683)
For rooms with a name we can skip fetching a full room summary, as we
don't need to calculate heroes, and instead just fetch the room counts
directly.

This also changes things to not return counts and heroes for non-joined
rooms. For left/banned rooms we were returning zero values anyway, and
for invite/knock rooms we don't really want to leak such information
(even if some of is included in the stripped state).

Speed up sliding sync by reducing amount of data pulled out of the database for large rooms.
