SimplePie: Return nothing and throw an error in SimplePie_Sanitize when DOMDocument is disabled. 

Note that when SimplePie is used through the WordPress fetch_feed() function, we use kses rather than SimplePie_Sanitize, which removes the dependency on DOMDocument. This change is only for plugins using SimplePie directly.

props rmccue. fixes #21990.
