Cocoa: Fix backing store performance regression.
Commit 916dfcb8 introduced a regression where QNSView would hold a copy if the backing store QImage, which would cause a detach and deep copy if/when the image was painted on while the copy was held. Revert back to the previous share-by-pointer scheme.
