Add WTF::crossThreadCopy(T&&) to utilize String::isolatedCopy() &&

&&-qualified String::isolatedCopy() has a optimization which
just does WTFMove if it isSafeToSendToAnotherThread which means
the object hasOneRef.
https://trac.webkit.org/browser/webkit/trunk/Source/WTF/wtf/text/WTFString.cpp?rev=246531#L640

WTF::crossThreadCopy is using only &-qualified isolatedCopy.
To use the optimization, add WTF::crossThreadCopy(T&&).
