bundle config contains (path,manifest) pairs of embedded APKs

If an APEX contains APKs and the manifest package name of the APKs are
overridden (either via override_android_app
orPRODUCT_MANIFEST_PACKAGE_NAME_OVERRIDES), that the path to the APK
(relative in the APEX) and the overridden manifest package name is
recorded in the bundle config file.
