This adds support for specifying options needed to deal with phone display panel pecularities (ex. screen curves, notches, punch holes) This is implemented as settings in ~/.config/plasmamobilerc, which can set panel heights, paddings, and center spacings to duck display cutouts. The pixel values are scaling independent, and so are not affected when the display scaling is changed. This is then exposed over DBus, so that components from outside of plasmashell (ex. KWin) can access it easily without needing to connect to kscreen themselves. Each screen is exposed as a single object. Currently support is only added in the status bar and the navigation panel. Currently all screens have the settings applied. In the future, we may want to limit this just to the internal screen (?) --- This also adds a "devices" folder (in `devices/configs`) where per-device configs can be set. This is installed to `/usr/share/plasma-mobile-device-configs`. In `plasmamobilerc` (installed to `/etc/xdg/plasmamobilerc`, or `~/.config/plasmamobilerc`), envmanager will read: ```toml [Device] device=oneplus-enchilada ``` for the device config to use and write its settings to `~/.config/plasma-mobile/plasmamobilerc`.
