FIX: trigger_multiple restart

Description

This PR introduces a fix to the trigger_multiple entity, adding the ability to restart the trigger after being deactivated. Previously, trigger_multiple entities did not properly restart when required, potentially leaving certain game mechanics broken.

Changes:

• New Restart Mechanism: The CTriggerMultiple::Restart function has been implemented to handle the reinitialization of the trigger.
• Trigger Restart Logic: When invoked, the Restart function stops the current trigger and spawns it again, allowing it to be reused.
• Improvement to Spawn Logic: Added logic to correctly reset the trigger in the Spawn method for proper functioning after restart.

Fixes:

• Trigger Reset Issue: This fix addresses the problem where trigger_multiple entities wouldn't restart, preventing certain game events from being triggered multiple times as intended.

Impact:

• This fix enhances the functionality and reliability of the trigger_multiple entity, allowing it to function as expected in multiplayer games with multiple activations.

@overl4y Can you provide an map to demonstrate that restarting trigger_multiple is necessary?
need to be careful to this PR, because it can break behavior a lot of maps

It's widely used in zombie escape maps to activate an ambient_generic, func_door, func_breakable, func_tracktrain and a trigger_hurt at the end of the map. But when the round ends quickly, it breaks the entire trigger_multiple flow.
