ipv4: drop ipv6_stub usage and use direct function calls
As IPv6 is built-in only, the ipv6_stub infrastructure is no longer
necessary.
The IPv4 stack interacts with IPv6 mainly to support IPv4 routes with
IPv6 next-hops (RFC 8950). Convert all these cross-family calls from
ipv6_stub to direct function calls. The fallback functions introduced
previously will prevent linkage errors when CONFIG_IPV6 is disabled.
