Ensure that all actions are compared to fixed point in time (ie. world update start) (#18910)

- Actions will not be dependent on processing moment
- Increased GameObjects cooldown resolution to milliseconds, fixes arming time of traps to be exactly one second and not something from range (1000, 1999)
- Created GameTime namespace and UpdateTime class and moved there some code out of world
