wacom: Instaurate calibration

The "area" setting has a different treatment in the gsettings-desktop-schemas
tablet schema, the 4 double values express the padding (in unitless 0..1
range) on each of the sides of the tablet. It's been done so we don't rely
on input/output units, which we might have not the luxury to access.

Besides that, the dependency on GsdWacomDevice has been cleared.
