[UE4] Set Input Mode (three mouse input modes)

 

The first type: can control both the game interface and the UI interface (this is what we want now);

The second type: the mode that can only control the game interface is the mode that controls the rotation of the current viewing angle (this is the original mode when the mouse is not called);

The third type: can only control the UI interface (this mode can only operate the buttons on the UI interface and the like, and the game interface is fixed there).
