Message:

Customize: Opt to disable IE8 support via conditional comments instead of using unreliable Array.prototype.indexOf feature detection.

Deprecate/remove WP_Customize_Manager::customize_preview_html5() and remove document.head polyfill, both of which were only in place for IE8 support.

Props ryankienstra, westonruter.
Fixes #38021.
