Gary Pendergast 83c3e3e00e Embeds: Add oEmbed provider support.
For the past 6 years, WordPress has operated as an oEmbed consumer, allowing users to easily embed content from other sites. By adding oEmbed provider support, this allows any oEmbed consumer to embed posts from WordPress sites.

In addition to creating an oEmbed provider, WordPress' oEmbed consumer code has been enhanced to work with any site that provides oEmbed data (as long as it matches some strict security rules), and provides a preview from within the post editor.

For security, embeds appear within a sandboxed iframe - the iframe content is a template that can be styled or replaced entirely by the theme on the provider site.

Props swissspidy, pento, melchoyce, netweb, pfefferle, johnbillion, extendwings, davidbinda, danielbachhuber, SergeyBiryukov, afercia

Fixes #32522.
