    PackageManager: allow build-time disabling of components

    Allow components to be specified as disabled at build time
    (applied on boot).

    This allows stock OTA components to be marked as disabled in
    CM builds.

    PM: Allow disabling components per-device

    * Introduce a new overlayable string-array
      "config_deviceDisabledComponents"
    * This is equally used to disable components per-device, e.g.
      NearbyMessagingService
    * At the same time, rename config_disabledComponents to
      config_globallyDisabledComponents to reflect the difference
