Issue description

The function is_mouse_button_pressed() works with mouse indices like 1 for left mouse button, it does not for 6 or 7 which are wheel left and right:

Input.is_mouse_button_pressed(MOUSE_BUTTON_LEFT) # Returns true if pressed, false if not
Input.is_mouse_button_pressed(MOUSE_BUTTON_WHEEL_LEFT) # Always returns false

Steps to reproduce

func _process(delta):
    print(Input.is_mouse_button_pressed(MOUSE_BUTTON_WHEEL_LEFT))

Run and press your mouse wheel to the left.

The mouse wheel events are sent in a single frame, the down and up events are sent at once, by design, this should probably be documented better though

That makes sense for down and up scrolling but it feels like the left/right wheel buttons are handled the same way, which should not be the case.
