Core/Common: Add a std::chrono interface to TimeTrackerSmall

New methods:
TimeTrackerSmall(Milliseconds expiry);
void Update(Milliseconds diff);
void Reset(Milliseconds expiry)
Milliseconds GetExpiry() const

Removed methods:
int32 GetExpiry() const

Also add basic unit tests.

Core/Scripts: Use std::chrono interface of TimeTrackerSmall
