Move mobile signal indicator to QS footer.

- Change mobile data tile to a static icon with mobile data indicators
- Add the status bar mobile network signal icon to QS footer
- Show SIM status in the carrier text in the QS footer only if the
status is not simply "No SIM card" since that status is shown in the
secondary text of the mobile data tile
