Title:
  [gsd-rfkill] WwanEnabled never get synced

Status in gnome-settings-daemon source package in Kinetic:

Bug description:
  [ Impact ]

   * Sometimes on devices with WWAN card, whenever user presses the
  wireless function key (Fn+F8) or turn on the airplane mode radio
  button in Settings, the airplane mode will not be enabled, and the
  airplane mode icon is not shown in the status bar.

   * There is a unmerged upstream merge request that delivers the fix:
  https://gitlab.gnome.org/GNOME/gnome-settings-
  daemon/-/merge_requests/310

  It works perfectly well on several Lenovo laptops with WWAN cards.
  The root causes is that the value of "WwanEnabled" under "org.freedesktop.NetworkManager" is not synced correctly, gsd-rfkill should listen to "g-properties-changed" instead of "g-signal" now.

  [ Test Plan ]

   1. Find a machine which has WWAN card.
   2. Boot the machine, and run rfkill list to see if WWAN is unblocked. if not use rfkill to unblock the WWAN, and reboot.
   3. Press the wireless media key (Fn+F8) or turn on the airplane mode radio button in Settings.
   4. The airplane mode should be enabled, but actually not.

  [ Where problems could occur ]

   * When user is using a very low version network-manager (< 1.20) that
  still broadcasting DBUS "PropertiesChanged" events on "g-signal"
  instead of the concurrent "g-properties-changed", the airplane mode
  will sometimes not be able to enable.

  [ Other Info ]

  1. About Ubuntu
  Description:    Ubuntu 22.04.2 LTS
  Release:        22.04
  Kernel:         6.1.0-1007-oem

  2. The version of packages:
  gnome-settings-daemon:
    Installed: 42.1-1ubuntu2.1

  network-manager:
    Installed: 1.36.6-0ubuntu2

  3. Expect:
  The function nm_signal(plugins/rfkill/gsd-rfkill-manager.c) is called, and manager->wwan_enabled is set to the correct value.

  4. Actual:
  The function nm_signal(plugins/rfkill/gsd-rfkill-manager.c) is never called, so manager->wwan_enabled is not synced, If machine has WWAN device(s), and the initial value of manager->wwan_enabled is true, it will never be able to switch to airplane mode.
