Script Loader: Add backward compatibility for JavaScript i18n globals and properties deprecated in WordPress 5.5.

The recommended approach for any plugins using these globals or properties is to switch to the newer `wp.i18n` functions.

In the meantime, this ensures that accessing any of these globals does not break the rest of the code on the page, and an appropriate warning message is logged to the JavaScript console.

Follow-up to: https://core.trac.wordpress.org/query?summary=~wp.i18n&milestone=5.5

Props omarreiss, peterwilsoncc, kbjohnson90, johnbillion, TimothyBlynJacobs, joostdevalk, ocean90, desrosj, SergeyBiryukov.
Fixes #51123.
Built from https://develop.svn.wordpress.org/trunk@48923
