refactor: add Packet::writePackedGuid, remove redundant static methods

Browse source 
Add writePackedGuid() to Packet class for read/write symmetry. Remove
now-redundant UpdateObjectParser::readPackedGuid and
MovementPacket::writePackedGuid static methods. Replace 6 internal
readPackedGuid calls, 9 writePackedGuid calls, and 1 inline 14-line
transport GUID write with Packet method calls.
