ApkResolution: Now takes into account apk abi when resolving.

Previously any apk found would be selected even if the abi did not match
the device, now an apk is only selected if it is compatible with the
device. Additionally the 'exact_abi' parameter has been added to allow only
selecting an apk if a devices primary abi's native code is present in
the apk, or there is no native code.
