Improvement of Shield and Battery

Shield: the function of setting the tilt angle of the handle, the shield and the weapon need to be set separately, and it's inconvenient to share the settings now.

Turret: the angle of rotation of the lens after zooming in can't be consistent with that before zooming in, and now it is consistent, which makes it difficult to aim at the target finely after zooming in; the up and down angle of rotation of the turret can be set to be inverted or not, and the current way will always be uncomfortable for a part of the players.
