Add the option to remove any new buttons a custom node adds to the right-click menu.

### Feature Idea

Hi, can we get the option to remove the extra crap custom nodes add to the right-click menu?
No offence to custom node makers, I just do not need all this clutter that I will never use, sometimes its really hard to find a button when there are 100 different ones, especially ones with emojis which is annoying.

Huge plus if we can also customize the ordering of the menu, but just allowing us to disable the custom buttons will be a huge help.

The issue names no source file, test, or entry point. Start by locating the code that builds the custom-node right-click menu and its existing settings, then determine how a user-facing disable option would be represented; done would be a working way to hide custom buttons, with ordering treated as a separate scope decision.
