This deprecates IPForward= setting, which unconditionally controled the global setting, even though it is a setting in .network file. Instead, this introduces new IPv4Forwarding= and IPv6Forwarding= settings both in .network and networkd.conf. If these settings are specified in a .network file, then the per-interface forwarding setting will be configured. If specified in networkd.conf, then the global IP forwarding setting will be configured. Closes #30648.
