[3/3] services/Telephony: Add Network Tiles

      Add an LTE tile and a 2G/3G mobile network tile.

      The LTE tile requires that at least one (1) of the following configs
      be present in the device's build.prop in order to show:
          telephony.lteOnCdmaDevice=1
          telephony.lteOnGsmDevice=1

      The 2G/3G tile toggles between 3G Only, 2G Only and 2G/3G.

      If LTE is turned on the 2G/3G tile is disabled (shows unknown).
      The reverse is also true, turning on the 2G/3G tile disables LTE tile.

Mobile Network Battery Saver Mode

When idle (screen off) switching to 2G can help extend
battery life as 2G generally uses less power than 3G or LTE.

    + 30 seconds after screen turns off, set network type to 2G
    + If a music player is active (playing), do not set network to 2G
    + When device is unlocked, reset to orignial network type
