Pass externalAccessibleFactory to SkiaSwingLayer.

[m-sasha]

Pass ComposeSceneAccessible correctly to SkiaSwingLayer (like we do to SkiaLayer) so that NativeAccessibleFocusHelper can do its trick.

import javax.swing.JButton
import javax.swing.JFrame
import javax.swing.JPanel
import javax.swing.SwingUtilities

fun main() {
    System.setProperty("compose.swing.render.on.graphics", "true")

    SwingUtilities.invokeLater {
        val frame = JFrame()
        frame.setSize(800, 200)
        frame.defaultCloseOperation = JFrame.EXIT_ON_CLOSE

        val panel = JPanel(GridLayout(1, 4))
        panel.add(JButton("Swing Button"))
        panel.add(ComposePanel().apply {
            setContent {
                Button(onClick = {}) { Text("Compose Button")}
            }
        })
        panel.add(JButton("Swing Button"))
        panel.add(ComposePanel().apply {
            setContent {
                Button(onClick = {}) { Text("Compose Button")}
            }
        })

        frame.contentPane.add(panel)

        frame.isVisible = true
    }
}
