Before Xcode 14 the `objc_super` struct definition in the SDK headers looked like this:
```
#if !defined(__cplusplus) && !__OBJC2__
/* For compatibility with old objc-runtime.h header */
__unsafe_unretained _Nonnull Class class;
#else
__unsafe_unretained _Nonnull Class super_class;
#endif
```
With Xcode 14 however the iOS/tvOS SDK header was changed to only define `super_class`, but the MacOSX SDK stayed the same.
Added CMake detection of this case so we can compile both on older and newer Xcode SDKs across platforms.

@carlossanlop since this is a build change, I think it can go right in after CI completes. Can you merge it for us? |

Backport of #76433 to release/7.0
/cc @akoeplinger
Customer Impact
This impacts our official build, without it we can't build iOS/tvOS with Xcode 14 as soon as it rolls out to AzDO.
Testing
Local tests with Xcode 14 confirmed it fixes the issue.
Risk
Low.
IMPORTANT: Is this backport for a servicing release? If so and this change touches code that ships in a NuGet package, please make certain that you have added any necessary package authoring and gotten it explicitly reviewed.
