Customizer: Nav Menus JS cleanup, first round * In `init`, settings should be fresh and set to default values before extending * When looping via `_.each`, pass `this` as 3rd arg to bind context * Settings should be encapsulated in the module, instead of being exposed as static class props * `currentRefreshMenuInstanceDebouncedCalls` should be encapsulated and renamed, instead of being the longest symbol in the entire codebase See #32911.
