[macOS] Move the window if there is no title bar (#382)

Browse source 
* macOS: Move the window if there is no title bar

On macOS by default windows can only be moved by clicking and
dragging on the titlebar, if we spawn a window without one we
need to set the `movableByWindowBackground` property.

Partial fix for #368

* macOS: Make moveByWindowBackground optional

Implements setting the property via WindowBuilderExt:

    WindowBuilder::new()
        .with_decorations(false)
        .with_movable_by_window_background(true)

* Update CHANGELOG
