Add a label to /proc/config.gz, so we can distinguish this file from
other /proc files in security policy.
For now, only init is allowed read access. All others are denied.
TODO: clarify exactly who needs access. Further access will be granted
in a future commit.
Bug: 35126415
Test: policy compiles and no device boot problems.

In order to support platform changes without simultaneous updates from
non-platform components, the platform and non-platform policies must be
split. In order to provide a guarantee that policy written for
non-platform objects continues to provide the same access, all types
exposed to non-platform policy are versioned by converting them and the
policy using them into attributes.
This change performs that split, the subsequent versioning and also
generates a mapping file to glue the different policy components
together.
Test: Device boots and runs.
