Enforce app updatability in GenerateAndroidBuildActions

Remove part of the apex top down mutator by moving enforceAppUpdatability
to a check in GenerateAndroidBuildActions instead of mutating
dependencies.  This requires annotating app dependencies of updatable
apexes with `updatable: true` in the Android.bp files.
