basic tablet/phone/watch autodetection 

Until we're able to detect touchscreen itself, let's have a detection
based on a form factor of the device.

Tablets and handhelds are usually equiped with touchscreens, so as a
default enable touchscreen GUI there.

 - Windows and Linux supports autodetection.
 - Android is hardcoded as touch-based.
 - MacOS staying same as before without detection.

Heavily "inspired" by systemd way of handling detection.
