I’m encountering an issue when using AndroidViewBinding and I think it may be an point worth optimizing:
AndroidViewBinding ’s update block is invoked at least twice. Even when the update lambda is empty:

AndroidViewBinding(factory = AnyBinding::inflate) {
  // ...
}

Maybe we can optimize it in the following way:
Since a new instance of update block is created every recomposition, it’s better to remember it before passing it to `AndroidView`:

val updateBlock = remember {
  { viewBindingRef.value?.update() }
}
AndroidView(
    factory = viewBlock,
    modifier = modifier,
    update = updateBlock
)

And, since
fragmentContainerViews.clear()
can cause a recomposition, it’s also better to check whether fragmentContainerViews is empty before clear it:

if (fragmentContainerViews.isNotEmpty()) {
  fragmentContainerViews.clear()
}

Thus, when there’s no Fragment in the inflated layout, no recomposition will be triggered.
