[SYCL] Remove duplicated calls for event returned from handler::finalize (#19263)

Since 0a27e3f for an event returned from handler::finalize() called
event_impl::create_device_event() instead of
create_completed_host_event(). As identified @slawekptak, after this
there is no need for setQueue() and setContextImpl() calls, as the ctor
did the work already.
