Customizer: Remove additional wrapper element around `wp_nav_menu()` which broke some theme designs. 

Also includes these related changes:
* Export `oldContainer` and `newContainer` among the `customize-preview-menu-refreshed` event params for themes to be able to more easily re-initialize the DOM elements.
* Improve performance for partial refresh by only sending settings related to the menu being previewed.
* Fix previewing of menu assigned to Custom Menu by exporting a menu `term_id` as opposed to an object, as the former is more stable for comparing in in args hashes.
* Do full refresh of preview when nav menu unassigned so that the layout can be updated.
* Harden conditions for when partial refresh is eligible for a `wp_nav_menu()` instance.

Fixes #32841.
