Applayer plugin 5053 v2.10

[catenacyber]

Link to ticket: https://redmine.openinfosecfoundation.org/issues/
Preliminary work for https://redmine.openinfosecfoundation.org/issues/5053

Describe changes:

• get ready to use dynamic number of app-layer protos for some global arrays : run modes and output

Small PR that should be good in itself.

#11373 next round

Based on #11554 with needed rebase to get green CI

Still more work to do : I guess stack allocated arrays are fine, but the global variables cf git grep '\[ALPROTO_MAX' in

• app-layer-detect-proto.c
• app-layer-frames.c
• app-layer-parser.c
• app-layer-protos.c
• app-layer.c
  need to be allocated and freed, with taking care of the initialization order, so that we know ALPROTO_MAX final value...

And then take remaining commits out of #11321
And supply an example of an app-layer plugin
