Elevation of XML components is not taken into account

[florentmaitre]

See OdsBottomNavigation XML demo for an example:

This is due to the fact that the Surface which contains the composable content in OdsAbstractComposeView clips its content to its bounds.
To fix this we could either:

1. Add an elevation to the Surface to mimic the bottom navigation elevation. This would mean adding an elevation parameter to OdsTheme which is not the preferred solution.
2. Use LocalContentColor(and maybe other composition locals) instead of a Surface in OdsTheme to propagate colors properly.

We also need to update the ViewDataBinding method in app:

AndroidView(
    factory = {
        binding.bind()
        binding.executePendingBindings()
        binding.root
    },
    update = {
        binding.bind()
        binding.executePendingBindings()
        (binding.root as? ViewGroup)?.clipChildren = false
    }
)
