Revert "Remove mobile network settings related declaration"

This reverts commit 93a9f8faac4630708ebf927e9cce091188cebe2a.

Reason for revert: <The new mobile network settings have not cherry-picked to AOSP, the mobile network settings page can't be opened with this CL. So just revert this CL and submit one to the internal master>
