FlashLightVisualizer refactor + low power handheld light light radius fix (#11768)

* refactor: Removes FlashLightVisualizer (based on obsolete code) in favor or merging its functionality with HandheldLightComponent
fix: Low power lighting radius animations for lanterns, floodlights and flashlights now properly restore the original light radius when going back to full power

* refactor: Use the LightBehaviour component to animate HandheldLights
refactor: Remove unneeded HandheldLight definitions in some yaml files (already inherited by parents)
fix: Properly change the server side PointLightComponent Enabled property when turning HandheldLights on/off
feat: ReverseWhenFinished property on Fade light behaviours

* Empty commit to rerun CI with the new engine PR

* fix: Restore the correct HandheldLight addPrefix property, whoops

* refactor: blinkingBehaviourID -> blinkingBehaviourId, radiatingBehaviourID -> radiatingBehaviourId
