Add Xsettings support, for setting scaling related settings

Browse source 
This allows for most GTK and Qt apps to be scaled properly.
In the case of mixed DPI, it will default to using the smallest monitor scale.

which is likely after your compositor is started if it supports systemd.
## Scaling/HiDPI
On HiDPI displays, xwayland-satellite windows may have small text. Because HiDPI on X11 is very application dependent and hard to solve,
xwayland-satellite doesn't make an attempt to do it for you. However, the same methods that would normally work on X11 should also work
with satellite. See [the Arch Wiki on HiDPI](https://wiki.archlinux.org/title/HiDPI) for a good place start.
For most GTK and Qt apps, xwayland-satellite should automatically scale them properly. Note that for mixed DPI monitor setups, satellite will choose
the smallest monitor's DPI, meaning apps may have small text on other monitors.
Other miscellaneous apps (such as Wine apps) may have small text on HiDPI displays. It is application dependent on getting apps to scale properly with satellite,
so you will have to figure out what app specific config needs to be set. See [the Arch Wiki on HiDPI](https://wiki.archlinux.org/title/HiDPI) for a good place start.
Satellite acts as an Xsettings manager for setting scaling related settings, but will get out of the way of other Xsettings managers.
To manually set these settings, try [xsettingsd](https://codeberg.org/derat/xsettingsd) or another Xsettings manager.
## Wayland protocols used
The host compositor **must** implement the following protocols/interfaces for satellite to function:
