Move out allowlists for com.android.cellbroadcast

This change separates out the allowlist for the
com.android.cellbroadcast mainline module. This apex bundles two apks
(CellBroadcastApp and CellBroadcastServiceModule) that have regular
apk counterparts for non-mainline devices.
The allowlists are now in the projects which contain the source code for
the respective APKs, and are marked as dependencies for them
