DMS Configs in LUA

[adonespitogo]

I just started configuring my old linux desktop to use Niri and DMS, in preparation for using it in my newly ordered lenovo laptop that's still in transit. I just realized that some settings like battery are not applicable in both hardware. If the config files were in lua, I would be able to share the same config and just add a if/else condition to use battery/power settings only if the hardware is my laptop and disable it in my desktop.
