[llvm][DebugInfo][ObjC] Make sure we link backing ivars to their DW_TAG_APPLE_property (#165409) Depends on: * https://github.com/llvm/llvm-project/pull/165373 When an Objective-C property has a backing ivar, we would previously not add a `DW_AT_APPLE_property` to the ivar's `DW_TAG_member`. This is what was intended based on the [Objective-C DebugInfo docs](https://github.com/llvm/llvm-project/blob/main/llvm/docs/SourceLevelDebugging.rst#proposal) but is not what LLVM currently generates. LLDB currently doesn't ever try linking the `ObjCPropertyDecl`s to their `ObjCIvarDecl`s, but if we wanted to, this debug-info patch is a pre-requisite.
