[iOS] Add size update for Shell Popup Overlay after rotation

[cat0363]

Description of Change

When the terminal is rotated while the Flyout of Shell is displayed, the size of the overlay does not
change from the size before rotation. In this PR, we will be updating the size of the overlay after
rotation so that the overlay appears as intended.

Override the ViewWillTransitionToSize method to update the Tapoffview's Frame on rotation detection.
This will allow the size of the overlay portion to update on rotation. I needed to override the ViewWillTransitionToSize
method, so I added the definition to PublicAPI.Unshipped.txt.

[src\Controls\src\Core\PublicAPI\net-ios\PublicAPI.Unshipped.txt]

~override Microsoft.Maui.Controls.Platform.Compatibility.ShellFlyoutRenderer.ViewWillTransitionToSize(CoreGraphics.CGSize toSize, UIKit.IUIViewControllerTransitionCoordinator coordinator) -> void

[src\Controls\src\Core\PublicAPI\net-maccatalyst\PublicAPI.Unshipped.txt]

~override Microsoft.Maui.Controls.Platform.Compatibility.ShellFlyoutRenderer.ViewWillTransitionToSize(CoreGraphics.CGSize toSize, UIKit.IUIViewControllerTransitionCoordinator coordinator) -> void

[src\Controls\src\Core\Compatibility\Handlers\Shell\iOS\ShellFlyoutRenderer.cs]

public override void ViewWillTransitionToSize(CoreGraphics.CGSize toSize, UIKit.IUIViewControllerTransitionCoordinator coordinator)
{
    base.ViewWillTransitionToSize(toSize, coordinator);

    coordinator.AnimateAlongsideTransition((IUIViewControllerTransitionCoordinatorContext obj) => 
    {
        // Before rotation
    }, 
    (IUIViewControllerTransitionCoordinatorContext obj) => 
    {
        // After rotation
        if (IsOpen)
        {
            TapoffView.Frame = View.Frame;
        }
    });
}

Below is the execution result.

The solution I posted last time is not beautiful because the overlay is temporarily drawn in the size
before rotation when the terminal is rotated. To solve this problem, set the post-rotation size to
TapoffView before rotation.

public override void ViewWillTransitionToSize(CGSize toSize, IUIViewControllerTransitionCoordinator coordinator)
{
    base.ViewWillTransitionToSize(toSize, coordinator);

    coordinator.AnimateAlongsideTransition((IUIViewControllerTransitionCoordinatorContext obj) =>
    {
        // Before rotation
        if (IsOpen)
        {
            TapoffView.Frame = new CGRect(View.Frame.X, View.Frame.Y, View.Frame.Width, View.Frame.Height);
        }
    }, null);
}

Below is the execution result.

With this fix, overlays are no longer drawn at their pre-rotation size.

@samhouts, A stale tag has been added, but has the issue been resolved?
Could you please tell me in which version the issue was resolved?

[samhouts]

@cat0363 The stale label is just an easy way for us to query PRs that haven't been updated in a while. This isn't resolved to my knowledge because this PR hasn't been merged. Thanks for your patience!

[cat0363]

@samhouts , Thank you for your reply despite your busy schedule.
Your comment made me understand that the stale label serves as a marker.
I was worried that this label would cause it to be closed if no action was taken.
I will wait until the review of this PR starts.
