OmniLib: Introduce OmniRom SDK

 * omnilib-res app will be installed to system/frameworks for the futur internal ressources add-on
 * OmniLib java_library will be installed to system/frameworks for the futur internal java/aidl add-on
 * The OmniPreference android_library need to be moved outside system/frameworks  because of some nested dependency breakage
