Hide the Metal layer when the SkiaLayer becomes hidden.

[m-sasha]

• When the visibility of the SkiaLayer changes, notify the Redrawer.
• MetalRedrawer sets the hidden flag of the layer accordingly. see https://developer.apple.com/documentation/quartzcore/calayer/1410838-hidden?language=objc

This should fix JetBrains/compose-multiplatform#2656

Tested manually on Mac OS X Ventura 13.2.1 with this Compose code:

fun main() = SwingUtilities.invokeLater {
    val parentJPanel = JPanel(BorderLayout())

    parentJPanel.add(
        BorderLayout.CENTER,
        ComposePanel().apply {
            setContent {
                Box(
                    modifier = Modifier.fillMaxSize(),
                    contentAlignment = Alignment.Center
                ){
                    Text(
                        "Hello World",
                        modifier = Modifier.clickable{
                            parentJPanel.isVisible = false // <- this hides this JPanel, but the button stays visible on screen
                        }
                    )
                }
            }
            setSize(500, 500)
        }
    )

    parentJPanel.isFocusable = true;

    JFrame().apply {
        setSize(800, 600)
        contentPane.add(parentJPanel)
        isVisible = true

        contentPane.addMouseListener(object: MouseAdapter(){
            override fun mouseClicked(e: MouseEvent?) {
                parentJPanel.isVisible = true
            }
        })
    }
}
