Customizer: Introduce an API to create WP_Customize_Settings for dynamically-created settings.

* Introduce WP_Customize_Manager::add_dynamic_settings() to register dynamically-created settings.
* Introduce `customize_dynamic_setting_args` filter to pass an array of args to a dynamic setting's constructor.
* Add unit tests for WP_Customize_Manager and WP_Customize_Widgets.
* See WP_Customize_Widgets as an example.
