[Performance] Reduce Adventure S2S Chatter to World

[Akkadius]

Description

This is a performance adjustment for World where 3k players and 1,800 zoneservers showed strain on World. A grand majority of the CPU load (98%) this was shown to be TCP chatter (server to server).

I ran S<->S packet logging in world and found the following data. This change will be one of several found from these results. https://gist.github.com/Akkadius/12b57fadbbe21ea9a46b854c62cc3a65#file-world-s2s-1m-md

For this PR - this targets the following packets and should reduce chatter by upwards of 100% in the case that most players are not in adventures in most servers.

• ServerOP_AdventureDataRequest (361 packets in a minute - 6 packets/s received from zones)
• ServerOP_AdventureZoneData (41 packets a minute - 7 packets/s received from zones)

Type of change

• Optimization

Testing

Loaded into a zone, no query errors, no packet sent
