Enable passing Amcrest/Dahua signals through as HA events (#49004)

Some of the compatible hardware sends event signals that wouldn't map
well to entities, e.g. NTP sync notifications, SIP registering
information, or « doorbell button pressed » events with no « return to
rest state » matching event to have a properly behaved binary sensor.

Instead of only monitoring specific events, subscribe to all of them,
and pass them through (in addition to handling them as before if they
correspond to a configured binary sensor).

Also bump python-amcrest to 1.7.2. Digest of the changes:

* The library now passes through the event data instead of just presence of a
 "Start" member in in.
* Connection to some devices has been fixed by not throwing the towel on
  minor errors.
