[Filebeat] Panw module number of script compilation

[yukshimizu]

I've been working with a user who is trying to ingest Palo Alto FW's logs with the Filebeat Panw Module. And, they face "Too many dynamic script compilation" errors when ingesting a volume of events.

I checked the pipeline included in the module and found that the pipeline included a lot of if conditions which were treated as individual script.

Very similar issue has been already reported #49763. It would be better to take some drastic measures, however, if it is difficult, some walkaround should be documented like the case of Cisco ASA module #14236.
