Update the VPN icon to reflect the validation status of the VPN network

This change enhance the VPN user experience by introducing a icon in
the system status bar. Upon internet validation failure of an active VPN
connection, this icon seamlessly replaces the original VPN icon,
ensuring users are promptly informed of any connectivity issues.

SecurityControllerImpl#dump now includes network properties
(interface name and validation status) for monitored networks:
...
    SecurityControllerImpl:
    -------------------------------------------------------------------
    SecurityController state:
      mCurrentVpns={0=18c66e22216}
      mNetworkProperties={110={wlan0, true}, 111={ipsec199, true}}
...

The primary focus of this commit is the implementation of the icon
replacement logic. The design of the new icon will be addressed in a
subsequent commit within this Topic.

Bug: 302424768
Test: manual test to verify that the VPN icon accurately reflects the
validation status of the VPN connection.
