Link to redmine ticket: https://redmine.openinfosecfoundation.org/issues/5816

Previous PR: https://github.com/OISF/suricata/pull/10264

Disclaimer: this code triggers a stack use after scope error related, I think, to how I'm trying to "automate" the counter ids registration. I'll point out in the code

Describe changes:

• encode valid exception policy stats
• extract exception policy types to its own header file
• start documenting exception policy stats counters
• better highlight what exception policies are valid with which exception scenarios
• try to use array and struct for Exception Policy Counters

TODO:

• carefully review if we are not trying to log counters for cases when exception policies are not valid (such as specific situations in IDS or IPS).
• figure out how to apply same logic used for other stats counters for per-app-proto app-layer error exception policy stats
• better align stats.log - as the new counters size character is longer than what we currently have in the stats
• update the json.schema to include delta counters
• fix commit history
