Perform IGMPv2 when joining IPv4 multicast groups
Added headers, stats, checksum parsing capabilities from RFC 2236 describing IGMPv2. IGMPv2 state machine is implemented for each condition, sending and receiving IGMP Membership Reports and Leave Group messages with backwards compatibility with IGMPv1 routers. Test: * Implemented igmp header parser and checksum calculator in header/igmp_test.go * ipv4/igmp_test.go tests incoming and outgoing IGMP messages and pathways. * Added unit test coverage for IGMPv2 RFC behavior + IGMPv1 backwards compatibility in ipv4/igmp_test.go. Fixes #4682 PiperOrigin-RevId: 343408809
