PR: Make CodeEditor mouse shortcuts configurable.

[athompson673]

Description of Changes

Makes CodeEditor mouse shortcuts / modifiers configurable.

• Wrote at least one-line docstrings (for any new functions)
• Added unit test(s) covering the changes (if testable)

• Included a screenshot or animation (if affecting the UI, see Licecap)

Implementing multi-cursor editing (#22996) added new mouse click functionality which was bound to Ctrl-Alt Click. In other popular IDEs, the mulit-cursor interaction is Alt Click, however Spyder had already configured Alt Click to jump within a document (simulates hovering / clicking the scrollflag area). In order to allow users to choose whether to keep the original Spyder behavior, or to change the mouse interaction to be more similar to other IDEs, we need to add the ability to configure the mouse modifier keys.

@ccordoba12 I took a first shot at making a UI for editing mouse shortcuts, what do you think?

• Should the key names (checkboxes) be translated and/or customized per OS?
• Should any of the shortcut names be adjusted?
• Should it be a different UI entirely? :P

I do still have to add in some sort of validation to prevent users from applying 2 shortcuts to have the same modifiers, but it's otherwise functional already.
