Rollup merge of rust-lang#75150 - nanpuyue:deprecate_to_ipv6_compatib…

…le, r=LukasKalbertodt Add a note for Ipv4Addr::to_ipv6_compatible Previous discussion: rust-lang#75019 > I think adding a comment saying "This isn't typically the method you want; these addresses don't typically function on modern systems. Use `to_ipv6_mapped` instead." would be a good first step, whether this method gets marked as deprecated or not. _Originally posted by @joshtriplett in rust-lang#75150 (comment)
