Fix vehicle serialization during races (#1122)

Browse Source 
* Fix vehicle serialization during races

- Add missing frame stats reading
- correct the inversion of rotation
- correct serialization order
- use proper dirty flags

Tested that racers are no longer sideways on certain vertical slopes and stay in sync throughout the whole race.

* Update ClientPackets.cpp

* Update ClientPackets.cpp

* Update VehiclePhysicsComponent.h
