[LHDM-2201] Header/Footer Custom classes/IDs

Summary

• Our team has a specific Smartling-related requirement to be able to assign class names and IDs to the logo, language switch link, and log in link in the Header and the logo in the Footer.

Update: After chatting, this has been simplified to only include the custom classes.

How to test

I ran yarn test:browser:update but the changes I saw locally didn't seem related to the PR changes or the build error. Any help deciphering that would be appreciated.
