Register mouse wheel listeners on the container rather than the compose content

[m-sasha]

The container is the common parent of the compose content (skia layer) and the interop views. This is needed to receive them even when they occur over an interop view.

Fixes https://youtrack.jetbrains.com/issue/CMP-1062/SwingPanel-breaks-vertical-scrolling

In WindowInputEventTest.receive buttons and modifiers I changed the check from exactly matching the keyboard modifiers to verifying that the expected modifiers are on. Because of a problem in AWT.

Testing

Tested manually and will add a unit tests.

fun main() = singleWindowApplication {
    val scrollState = rememberScrollState()
    Box(
        modifier = Modifier
            .fillMaxSize()
            .verticalScroll(scrollState)
    ) {
        Row(Modifier.fillMaxSize().height(2000.dp)) {
            SwingPanel(
                background = Color.Red,
                modifier = Modifier
                    .weight(1f)
                    .height(400.dp),
                factory = {
                    JPanel(BorderLayout()).also {
                        it.add(JLabel("Swing content"))
                    }
                },
            )
            Box(
                Modifier.weight(1f).height(400.dp).background(Color.Blue),
                contentAlignment = Alignment.Center
            ) {
                Text("Compose content")
            }
            VerticalScrollbar(
                modifier = Modifier.fillMaxHeight(),
                adapter = rememberScrollbarAdapter(scrollState)
            )
        }
    }
}

This should be tested by QA
