Subject: libcamera: timer: Bind timers to threads
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

The Timer instances are registered with the event dispatcher instance of
the CameraManager. This makes it impossible to use timers in other
threads.

Fix this by inheriting from Object, which allows binding instances to a
thread, and register them with the event dispatcher for the thread they
are bound to.
