Fix oEmbed when the provider only supports XML responses.

[20539] removed string casts that would have taken place on SimpleXMLElement
objects, which implement toString. Instead, convert the SimpleXMLElement object
to a stdClass object before we leave _parse_xml(), for consistency with the
simple object returned from _parse_json().

see #20246.
for trunk.
