https://redmine.openinfosecfoundation.org/issues/5044

Describe changes:

• adds a count option to multi-buffers, behaving like a keyword but syntax is email.received: count <3; instead of email.received; count: <3;
• adds other modes to multi-buffers like all, all_or_absent, nb`, and precise indexing

SV_BRANCH=OISF/suricata-verify#2634

Draft :

• Feedback about general design ?

#14279 needed rebase, #14345 good branch rebased

TODOs :

• update doc if design is agreed
• add support for all multi-buf keywords
• add more tests
• rustfmt removes one line in mod.rs
