Add WTF::crossThreadCopy(T&&) to utilize String::isolatedCopy() &&
https://bugs.webkit.org/show_bug.cgi?id=198957

Reviewed by Alex Christensen.

Source/WTF:

&&-qualified String::isolatedCopy() has a optimization path which
does just WTFMove if it isSafeToSendToAnotherThread which means
the object hasOneRef.

However, WTF::crossThreadCopy was using only &-qualified
isolatedCopy. To use the optimization, added
WTF::crossThreadCopy(T&&) overloading.

* wtf/CrossThreadCopier.h:
(WTF::crossThreadCopy): Added a overload of (T&&).
* wtf/CrossThreadTask.h:
(WTF::createCrossThreadTask): Removed explicit template arguments of crossThreadCopy.

Tools:

* TestWebKitAPI/CMakeLists.txt:
* TestWebKitAPI/TestWebKitAPI.xcodeproj/project.pbxproj:
* TestWebKitAPI/Tests/WTF/CrossThreadCopier.cpp: Added.
