Remove unnecessary thread-safety code from entity spawning

Browse Source 
Eliminated redundant locks and related comments in EntitySpawner and Entity classes, simplifying the spawn and remove queue handling. Also removed outdated comments in GameScreen regarding thread safety. These changes assume entity spawning and removal are no longer performed from multiple threads, improving code clarity and maintainability.
