config/output: Update output position in two passes

The modeset logic iterates over all outputs at the end, sets their new
position in the layout and takes a copy of its geometry that is later
referenced by layout and scene management code.

If one output is auto configured, then a later output that is manually
configured can lead to the first output being moved without the stored
geometry being updated.

Split this into two passes: The first pass finalizes the output config
and makes updates to the layout, while the second pass updates the copy
of the geometry and arranges things as a result of it.
