Add option to disable/mute the Compositor Output node

It will be very helpful to have the option to disable the output node in the compositor.

Often, after rendering and using the Output node, users need to re-render with different settings. However, when re-rendering, the existing outputs are overwritten, which can be problematic. The only workaround currently is to delete the Output node, which also removes its configured settings - such as file paths, names, and passes, requiring users to set everything up again from scratch or disable the compositor "use nodes" all together.

So it will be extremely useful to have the option to disable/mute the node. Also an option for manual execution will be very appreciated :)
