monitor-config-manager: Add clone_logical_monitor_config_list helper

Browse Source 
Add a clone_logical_monitor_config_list helper function for making a deep
copy of MetaLogicalMonitorConfig lists.

This is a preparation patch for honoring accelerometer value changes when
there is more than 1 monitor.
