meta-monitor-config: Look at an output's modes directly when assigning

Browse Source 
Going through the global mode pool and then checking if the mode is
available for a given output is pointless work since we can look at
the output's available modes directly.

This implicitly changes how we choose the default mode since, instead
of relying on the sort order of the global modes array, we now rely on
the sort order of the output modes array. Still not ideal, but at
least it makes more sense since the global array is essentially
unsorted.
