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.
