This gives us an easy way for the policy to refer to all existing or future types used for app private data files in type= assignments in seapp_contexts. Apply the label to all the existing types, then refactor rules to use the new attribute. This is intended as a pure refactoring, except that: - Some neverallow rules are extended to cover types they previous omitted; - We allow iorap_inode2filename limited access to shell_data_file and nfc_data_file; - We allow zygote limited access to system_app_data_file. This mostly reverts the revert in commitb01e1d97bf, restoring commit27e0c740f1. Changes to check_seapp to enforce use of app_data_file_type is omitted, to be included in a following CL. Test: Presubmits Bug: 171795911 Change-Id: I02b31e7b3d5634c94763387284b5a154fe5b71b4
