monitor-config-manager: honor accelerometer value changes when there is more than 1 monitor

Browse Source 
Modify create_for_builtin_display_rotation to lookup the
MetaLogicalMonitorConfig for the panel in the logical_monitor_configs
list instead of only working when there is only 1 monitor.

The goal of this change is to honor accelerometer value changes when there is
more than 1 monitor.

Note, since create_for_builtin_display_rotation is also used for handling the
"rotate-monitor" hotkey and this commit modifies the common path of
create_for_builtin_display_rotation this means that we will now also honor
"rotate-monitor" hotkey keypresses when there is more than 1 monitor and
update the builtin display rotation instead of ignoring "rotate-monitor"
hotkey keypresses when there is more than 1 monitor. If this is deemed
undesirable this is easy to fix, but I believe that doing things this way
is more consistent.
