Weston Ruter aa044b054e Customizer: Ensure that wp.customize.Widgets.savedWidgetIds is defined up front.
In 4.3 the widget controls were fully initialized up front along with the sidebar controls. The sidebar control depended (unnecessarily) on the widget control to ensure that `wp.customize.Widgets.savedWidgetIds` was defined. So after [34563] there could be a situation where the widgets are added/removed from a sidebar before their controls are initialized (if the sidebar section is never expanded), resulting in an error attempting to get a property off of an undefined value. So this change does the right thing and defines `savedWidgetIds` up front.

Also changes the `savedWidgetIds` variable type from an array to an object, to match how it is used as a dictionary lookup.

See #33901.
