Add WKRetainPtr helper class as private header
https://bugs.webkit.org/show_bug.cgi?id=37603 Reviewed by Anders Carlsson. WKRetainPtr is just like RetainPtr, but works for WK types instead of CF/NS types. * UIProcess/API/cpp: Added. * UIProcess/API/cpp/WKRetainPtr.h: Added. * WebKit2.xcodeproj/project.pbxproj: Add new file. * win/WebKit2.vcproj: Ditto.
