Message:

Customizer: Introduce customize_loaded_components filter to allow core components to be disabled.

Also move style rule from customize-nav-menus.css to customize-controls.css so that widgets button is properly styled when nav_menus component is excluded from loading. See [35304]. See #33327.

Props westonruter, DrewAPicture.
Fixes #33552.
