Reason for change: Firewall rules to forward the traffic and the port for wireguard communications are added. Test Procedure: Check the firewall rules with the respective traffic flow once the connection is established. Testing Done : Results are captured in RDKBNETWOR-76 Risks: None.

Pull request overview
Adds WireGuard-related firewall configuration so the device can accept WireGuard UDP traffic and permit traffic to traverse the wg0 tunnel interface.
Changes:
- Introduces new global config values for
wireguard_enabledandwireguard_portread fromsyscfg. - Adds iptables filter rules to ACCEPT traffic on
wg0and to open the WireGuard UDP listening port on the WAN interface.
