Refactor and convert `Linearizer` to async. This makes a `Linearizer`
cancellation bug easier to fix.
Also refactor to use an async context manager, which eliminates an
unlikely footgun where code that doesn't immediately use the context
manager could forget to release the lock.

The shared ratelimit function was replaced with a dedicated
RequestRatelimiter class (accessible from the HomeServer

Other properties were copied to each sub-class that inherited
from BaseHandler.

Also:
- change the REST endpoint to have a "S" on the end (so it's now /read_markers)
- change the content of the m.read_up_to event to have the key "event_id" instead of "marker".
