WIP wacom: Port to GTK4
Lots of stuff missing and probably broken.
wacom: Port CcDrawingArea input to gestures
We have a handy GtkGestureStylus to use here, which avoids direct
handling of GdkEvents.
wacom: Update current stylus tracking to GtkGestureStylus
Use the ::proximity signal to notice when we are being hovered with
a tablet stylus, and look up the tool from there.
The calibration utility was modified in cf408c27b0 to return unitless
padding measurements instead of axis values for storage in gsettings.
Unfortunately, the code still assumes in some places that it is working
with axes rather than paddings. This causes subtle math errors that
result in undesired cursor offsets after the calibration is applied.
Fortunately, this can be simplified, since tablet area is always reset
to the default state before starting calibration, we are sure that the
value will remain constant. Since both axes are in the same 0..1 scale,
calibration code doesn't need to swap X/Y back and forth to calculate
each axis scale.
Additionally, the code to get the calibrated axis values has been moved
into its own function along with a new function that returns padding
values suitable for consumption by g-c-c. All calculations are performed
internally in the 0..1 range.

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.
The name of the file was also changed to calibratorgui.c/h to avoid
it being inconsistent, this way it is no longer dependent on the
the technology.
