Hide SettingsSlice provider
Explicitly set the Settings SliceBroadcastReceiver to
be non-exported and remove the intent-filter.
Add a second provider: SliceRelayReceiver to receive
broadcasts from SysUI to alert Settings to potential
changes to bound Settings Slices. The new receiver is
exported, but only notifies changes to Settings, and
doesn't make any changes itself.
Test: boot, robolectric, Slicebrowser
