If an `@objc implementation extension` had a public stored property with an observer, Swift would print `@_hasStorage` on the extension. This is Not Good because in a module interface, an objcImpl extension appears to be an ordinary extension, and properties in ordinary extensions are not supposed to have storage. Suppress printing this attribute in objcImpl extensions to avoid this problem. Partially fixes rdar://144811653 by suppressing emission of bad attributes.
