Embeds: Fix oEmbed host script enqueueing on block-based themes.

This change fixes oEmbed host script enqueueing on front-end when using block themes.

It deprecates wp_oembed_add_host_js in favor of wp_maybe_enqueue_oembed_host_js. The action is still triggered in default-filters.php to ensure backward compatibility for websites that are removing the action. There is now a has_action() check in wp_maybe_enqueue_oembed_host_js() to see if wp_oembed_add_host_js() has not been unhooked from running at the wp_head action.

Follow-up to [52132], [52151], [52153], [52325].

Props swissspidy, westonruter, flixos90, kafleg.
Fixes #44632.
