Customize: Ensure state query params persist in preview through calls to `history.pushState()` & `history.replaceState()`. 

Allow history to be manipulated before DOM ready by sourcing state params from the current URL instead of from the `wp.customize.settings` object, since they will be the same anyway. This fixes a JS error since `wp.customize.settings` is not defined before DOM ready.

Amends [38810].
See #30937.
Fixes #38592.
