Removal and Replacement of the CryTimer (gEnv->pTimer) (#5409)

Replaced and removed the CryTimer (gEnv->pTimer). The new TimeSystem is a merger of the current time functionality found in the engine.

* Rename TimeSystemComponent.h/.cpp to TimeSystem.h/.cpp
* Adding New TimeSystem
* remove old timer cvars
* small improvements to the time system.
 - updated parts to use the time conversion functions.
 - in AdvanceTickDeltaTimes applying t_simulationTickScale is now uses doubles instead of floats.
* Replace gEnv->pTimer / ITimer usages with TimeSystem
* Updating usages of AZ::TimeMs{ 0 } and AZ::TimeUs{ 0 } to AZ::Time::ZeroTimeMs and AZ::Time::ZeroTimeUs
* red code the CryTimer
* using TimeUs instead of TimeMs is some cases + updating usages of old cvars to new
