Convert to Soong

See build/soong/ for more information.

As a byproduct, this moves mmc_utils from /system/xbin to /system/bin,
as Soong is not supporting installation into xbin. It also removes the
debug tag, so it's no longer installed by default on all eng and
userdebug builds.

Test: mmma external/mmc-utils
