Some macro-generated declarations are not being printed in the Obj-C/C++ generated header. Members introduced by attached `member` macros on a type appear to be fine, but those introduced by a attached `peer` or freestanding `declaration` macros don't show up. This change updates the header writer to call `getAllMembers` throughout instead of `getMembers`, which makes sure that everything gets collected. Likewise, we update the top-level logic from `getTopLevelDecls` to `getTopLevelDeclsWithAuxiliaryDecls` to pick up freestanding decls introduced at file scope. Fixes https://github.com/swiftlang/swift/issues/68170.
