Reworked permission UI on TV into the new side-panel leanback style

Reworked all the permission UIs on TV to mesh with the rest of the
settings rendered as leanback-styled side panels with title bars.
The permissions consist of the following components:
   * Each individual app permission listing
   ** Listing of all the permissions together with the apps using
   those permissions
