qcacmn: Add support to send connectivity logs from logging thread

Add support to send connectivity logs from g_wlan_logging thread.
Add new HOST_LOG_DRIVER_CONNECTIVITY_MSG event flag which wakes up
the gwlan_logging thread when set.
Also register connection manager callbacks to send the logging event.

Check if logging queue is empty whenever the gwlan_logging thread
is woken up and send the logs to userspace if the count doesn't
exceed the allowed threshold.
