✨ Add optional payload for middlewares

[aswetlow]

Proposed Changes

Adds the possibility to add an optional payload parameter to the middleware run method. The payload parameter is always of type AnyObject.

I also added some properties to the payload object in internal functions.

// middleware `event.ComponentTreeNode.executeHandler` 
{
   componentName: string;
   handler: string;
}

// middleware `event.$resolve` 

{
   resolvedHandler: string;
   eventName: string;
   eventArgs: ARGS extends unknown[];
}

// middleware `event.$delegate` 
{
   componentName: string;
   options: DelegateOptions;
}

// middleware `event.$redirect` 
{
   componentName: string;
   handler: string;
}

// middleware `event.$redirect` 
{
   componentName: string;
   handler: string;
}

// middleware `event.$send` 
{
   outputConstructorOrTemplateOrMessage:  string
      | OutputConstructor<OUTPUT, REQUEST, RESPONSE, this>
      | OutputTemplate
      | OutputTemplate[];
   handler: DeepPartial<OUTPUT['options']>;
}

Usage in Jovo apps.

app.hook('event.ComponentTreeNode.executeHandler', (jovo, payload) => {
  console.log(payload.componentName);
  console.log(payload.handler);
});

This would improve/fix mentioned in #1292
