support: Adapt IconPackPreference class from Launcher3

Pick and adapt the icon pack preference in order to work with
v7.support.

This class is generic and will let other classes further
implementations, for instance it's being used for
RecentsIconPackPreference so to set values inside another Preference
"holder".
