Fixes#14832
- Added an option in the editor settings/cursor to make the cursor move with right click.
- If the option is activated (true by default), a right click will move the cursor before displaying context menu.
- If there is a selection, a right click on it will keep it selected, a right click outside it will unselect it.
- The option is available in textEdit via an inspector property (or via GDScript): caret_moving_by_right_click
- The option is available in the script editor and the shader editor via the editor settings
- The documentation has been updated with the new property, and a few other entries in TextEdit.xml.
