Drop the Button.Type property

The button type was the physical button type, not the logically assigned
button number.

This property is basically unused and of questionable use anyway. GUI
applications would need to rely on drawings of the mouse anyway. Scripts don't
really care because ratbagctl uses the button index anyway. The only time this
matters is when we're looking at (human) device discovery. But often clicking
around is enough to figure out the index.

So let's drop this API on the assumption that it's not really needed and
maintaining and extending that enum forever is not necessary.

This is not a full purge, merely the DBus API that gets dropped.
