Rather than always including all rooms in range.
Also adds a pre-filter to rooms that checks the stream change cache to
see if anything might have happened.
Based on #17447

The basic idea is that we introduce a new token for a sliding sync
connection, which stores the mapping of room to room "status" (i.e. have
we sent the room down?). This token allows us to handle duplicate
requests properly. In future it can be used to store more
"per-connection" information safely.
In future this should be migrated into the DB, so its important that we
try to reduce the number of syncs where we need to update the
per-connection information. In this PoC this only happens when we: a)
send down a set of room for the first time, or b) we have previously
sent down a room and there are updates but we are not sending the room
down the sync (due to not falling in a list range)

Backfill events have a negative stream ordering, and so its not useful
to use to compare with other (positive) stream orderings.
Plus, the Rust SDK currently assumes `bump_stamp` is positive.
Introduced in: #17215
This caused us a minor bit of grief as the volume of logs produced was
much higher than normal

This is to address an issue in which `m.presence` results on initial
sync are not returning entries of users who are currently offline.
The original behaviour was from
https://github.com/element-hq/synapse/issues/1535
This change is useful for applications that use the
presence system for tracking user profile information/updates (e.g.
https://github.com/element-hq/synapse/pull/16992 or for profile status
messages).
This is gated behind a new configuration option to avoid performance
impact for applications that don't need this, as a pragmatic solution
for now.

As it gets used in sliding sync.
We basically invalidate it in all the same places as
`get_rooms_for_user`. Most of the changes are due to needing the
arguments you pass in to be hashable (which lists aren't)

Prior to this PR, remote downloads which did not provide a
`content-length` were decremented from the remote download ratelimiter
at the max allowable size, leading to excessive ratelimiting - see
https://github.com/element-hq/synapse/issues/17394.
This PR adds a linearizer to limit concurrent remote downloads to 6 per
IP address, and decrements remote downloads without a `content-length`
from the ratelimiter *after* the download is complete and the response
length is known.
Also adds logic to ensure that responses with a known length respect the
`max_download_size`.
