Shin Yamamoto 16e709e8ab Fix backdrop flickering (#449)
* Add test_updateBackdropAlpha
* Fix backdrop alpha's flickers in Maps.app

This issue occurs when swinging down a panel with all one's might.
The trigger is here.
```
    func floatingPanelWillEndDragging(_ vc: FloatingPanelController, withVelocity velocity: CGPoint, targetState: UnsafeMutablePointer<FloatingPanelState>) {
        if targetState.pointee != .full {
            owner.searchVC.hideHeader(animated: true)
        }
        if targetState.pointee == .tip {
>>>         vc.contentMode = .static
        }
    }
```
However, any library users expect to affect the backdrop by this code.
And then I reconsidered the reason why the backdrop alpha changes in
activateLayout(for:forceLayout:) and it's because the animation using
CAAnimation on v1.

Therefore I decided to move the point to change the backdrop alpha into
the move animation's completion handler.

And also the responsibility of `setBackdropAlpha(of:)` was moved into
`Core` because `Core` takes on a role of changing the backdrop alpha.
