https://redmine.openinfosecfoundation.org/issues/8262

Adds decoder for IGMPv1, v2, v3, plus RGMP. Adds igmp-csum keyword, igmp.hdr sticky buffer and igmp.type keyword. Misc other additions.

Replaces #14794

Basic v1, v2 and v3 header validation.

Ticket: OISF#8262.
So 'alert igmp ...' can work.
Add rule to decoder-events.rules to match on bad checksums.
Reordering of table and switch to match switch in parser.
RGMP is a dialect of IGMP that uses the same protocol structure,
but with some different values for the fields.

Detect this and log it differently.
