iOS: Add platform plugin option to debug window management

When the 'debugWindowManagement' option is enabled, e.g. by passing the
argument -platform ios:debugWindowManagement to the application, the
plugin will add a background color and outline to all QUIViews, as
well as draw a grid for the underlying QUIViewController. This makes
it easier to see where windows are placed when the window itself
doesn't draw anything, e.g. in unit tests.
