Comment:

 > Probably no need for so many functions.

 This is similar to slurping images / galleries from a content blob. There
 are so many different ways it can be in there, we need 6 extraction
 functions, and here they are:

 - `get_post_audio()` - wraps `get_children()`, returns attached audio,
 impl'd in #23282
 - `get_post_video()` - wraps `get_children()`, returns attached video,
 impl'd in #23282
 - `get_content_audio()` - slurps shortcodes out of the passed content and
 returns a list of lists: each shortcode can have multiple `<source>`s (the
 primary audio `<source>` and its fallbacks)
 - `get_content_video()` - slurps shortcodes out of the passed content and
 returns a list of lists: each shortcode can have multiple `<source>`s (the
 primary video `<source>` and its fallbacks)
 - `get_embedded_audio()` - returns a list: slurps embed HTML
 (`<object>`,`<embed>`,`<iframe>`) and HTML5 `<audio>` tags out of content,
 or if the content is a URL or starts with a URL, returns that as well
 - `get_embedded_video()` - returns a list: slurps embed HTML
 (`<object>`,`<embed>`,`<iframe>`) and HTML5 `<video>` tags out of content,
 or if the content is a URL or starts with a URL, returns that as well

 Patch updated. Unit Tests forthcoming.
