Summary Implements a CLAT (part of a larger 464XLAT ipv6 transition mechanism) in NetworkManager

NetworkManager now implements CLAT for the 464XLAT transition mechanism, auto‑detecting NAT64 prefixes via PREF64 router advertisements and exposing configurable properties for controlling CLAT behavior. The PR adds two new configuration options: ipv4.clat, defaulting to “no” (for now), and ipv4.dhcp‑ipv6‑only‑preferred, defaulting to “auto”. CLAT is implemented using an eBPF program.
