ObjC ivar metadata has up to now emitted an empty string for the ivar's objc type encoding. Conversely, ObjC property metadata is emitted with an objc type encoding. This changes the compiler to also emit an objc type encoding for ivars. The motivation for this change is for lldb to print ivars of classes declared in Objective-C but implemented in Swift, as defined in [SE-0436](https://github.com/swiftlang/swift-evolution/blob/main/proposals/0436-objc-implementation.md). Without the presence of type encoding for ivars, lldb is unable to present to the user the ivars/properties of instances of such classes. rdar://138569299
