Remove expedition includes from client header

Make quest compass a vec3 to remove include dependency

Quest compass location doesn't require a zone id since it can only be
set in the zone that it's drawn in. Drop the DynamicZoneLocation member
and forward declare to remove the dependency on header.

Move ExpeditionInvite struct to zone common header

Including expedition.h in client.h just to use the ExpeditionInvite struct
is an unnecessary header dependency that increases incremental build time.
This allows expedition classes to be forward declared in client header.
