Combine/Separate XYZ should be built into graph flow.

Using the Combine XYZ and Separate XYZ are such common parts of almost every geometry nodes graph that it becomes time-consuming to add them, even when you make them part of Quick Favorites. (see video for super rough mockup)

I'm proposing having a hotkey (button, double-click, whatever) that would make any 'unseparated' set of XYZ coordinates in a node 'fly out' into the separated components.

I might actually prefer if it simply added separate inputs to the original node though, reducing clutter.
