The Objective-C methods for Kotlin data class componentN methods
shouldn't have been generated in the first place -- the corresponding
Kotlin methods are required to make the destructuring work in Kotlin,
and don't help in Objective-C or Swift.
Calling them manually from Objective-C or Swift doesn't make much sense.
So now we deprecate this, in order to remove these methods from
Objective-C header completely later.
