Change shutterbutton hold behavior with grouptopic (#19263)

* skip stop on hold if grouptopic

If shutterbutton is defined with a grouptopic send on HOLD, there is no stop on releasing the button. All shutters will move to defined position

* do not stop on hold release if group submitt

If mqtt broadcast is defined on hold then release the hold button will not anymore stop the local shutter. All shutter will move to defined position
