Customize: Harden assignment of Customizer settings transports for selective refreshable widgets

Theme support for customize-selective-refresh-widgets can be added _after_ the logic for registering the settings for incoming widgets that have been changed. This is due to themes adding the theme support in after_setup_theme which is also the action where WP_Customize_Widgets::register_settings() is called. If these both happen at priority 10, which one is called first depends on which one was added first. The other issue is that at the time that WP_Customize_Widgets::register_settings() is called at after_setup_theme, it is called before widgets_init and thus no widgets are yet registered. This means that any settings registered at this point will always have a refresh transport even if the theme supports customize-selective-refresh-widgets, since the WP_Widget instance is not visible yet to see if it supports selective refresh.

The fix: Defer WP_Customize_Widgets::register_settings() from after_setup_theme to widgets_init at priority 95 when the widget objects have all been registered. Also, ensure that the preview filter for sidebars_widgets is added before the sidebars are iterated for adding the controls.

Props westonruter.
Fixes #36389.
