Rui Matos 9a076076c0 monitor-manager-kms: Add common modes
Some output devices only advertise their preferred mode even though
they're able to display others too. This means we can include some
common modes in each output's supported list.

This is particularly important for mirroring, since we can only mirror
outputs which are using the same resolution.
