config/output: reconfigure input devices on new output

Some input rules, like `map_to_output`, are dependent on a specific
screen being present. This currently does not work for hotplugged
outputs, or outputs that are processed after the input device is
initially probed.

This commit fixes both cases, by reconfiguring inputs on each output
addition.

Fixes #5231.
