Add stop/reset functionality to RepeatForever action

[dmytropaduchak]

Context

The RepeatForever action in Excalibur.js currently loops indefinitely, providing no built-in mechanism for resetting the action once it is in progress. In scenarios where more control over the flow of repeated actions is required (e.g., restarting the animation after a specific event or condition), developers are left without an efficient way to manage these actions.

• The current implementation of RepeatForever does not allow for resetting the action, which can be limiting for game developers who need more flexibility in controlling repeated actions.
• Developers may need to manually recreate or manage actions outside the RepeatForever context, leading to extra complexity and potential bugs.

Proposal

stop method

• This method will stop all actions in the repeat cycle, preventing further execution of the repeated actions while maintaining the current state of the actor.
• Once stopped, the action should remain halted until explicitly resumed or reset.

public stop(): void {
  this._stopped = true;
  this._actionQueue.getActions().forEach((i) => i.stop());
}

reset method

• This method will reset the RepeatForever action, allowing it to restart from its initial state. The actor will return to its default position, and the repeated actions will be reinitialized.
• After calling reset(), the repeated actions should begin again from the start, as if it was newly created.

public reset(): void {
  this._stopped = false;  
  this._actionQueue.reset();
}

@dmytropaduchak I think this is a great idea! I fully support this feature
