Do not revalidate window after resizing.

[m-sasha]

This revalidation was added in #442, but that problem no longer reproduces.

I'm not really sure why this revalidation causes Resizing the window using WindowState breaks the UI, but it doesn't appear to be needed.

Testing

Tested manually with

@OptIn(ExperimentalComposeUiApi::class)
fun main() {
    application {
        val state = rememberWindowState()
        var value by remember { mutableStateOf(0) }

        Window(onCloseRequest = ::exitApplication, state = state, undecorated = true) {
            Box(Modifier.fillMaxSize().background(Color.Yellow)) {
                Box(
                    contentAlignment = Alignment.Center,
                    modifier = Modifier.size(200.dp).offset(x = 10.dp, y = 10.dp).background(Color.Red)
                ) {
                    val windowInfo = LocalWindowInfo.current
                    Column(horizontalAlignment = Alignment.CenterHorizontally) {
                        Text("$value")
                        Text("${windowInfo.containerSize}")
                    }
                }
            }

            LaunchedEffect(Unit) {
                while (true) {
                    state.size = DpSize(700.dp, 500.dp)
                    value += 1
                    delay(DELAY)
                    state.size = DpSize(800.dp, 600.dp)
                    value += 1
                    delay(DELAY)
                }
            }
        }
    }
}

const val DELAY = 300L

This could be tested by QA
