Fuzz conf 3591 v2

[catenacyber]

Link to redmine ticket:
https://redmine.openinfosecfoundation.org/issues/3591

Describe changes:

• Adds a new fuzz target which takes config + signature + pcap as an entry

Draft : expecting feedback if this looks a good approach

Still to do :

• Make FuzzConfReload call more than app-layer stuff

#9531 with more config values (ssh hassh, ssl ja3)

Closing as stale, did not get feedback 😢 (and low priority versus fixing current bugs found by fuzzing anyways)
