Disable Lazy Loading for IFRAMES

After WordPress 5.7 is released, iframes will have the loading="lazy" attribute added by default. See Trac ticket 50756, and changeset 49808 for the actual implementations in core.

This plugin, for the short term, is a global disabling of lazy loading for all iframes, no matter their context.
