[Bug] GADRequestConfiguration setTagForUnderAgeOfConsent: unrecognized selector sent to instance

### [REQUIRED] Please fill in the following fields:

* Pre-built SDK from the: [website](https://firebase.google.com/download/cpp)
* Firebase C++ SDK version: 12.0.0
* Problematic Firebase Component: GMA
* Other Firebase Components in use: Auth, Analytics, Remote Config, Storage, Dynamic Links
* Platform you are using the C++ SDK on: Mac
* Platform you are targeting: iOS

### [REQUIRED] Please describe the issue here:

While trying to initialize AdMob, I call `firebase::gma::SetRequestConfiguration`, which ends up throwing an Objective-C exception stating: `-[GADRequestConfiguration setTagForUnderAgeOfConsent:]: unrecognized selector sent to instance 0x283a12640`

The issue is likely related to pull request: #1537 where it states among changes:

Breaking changes in GADRequestConfiguration:
- setSameAppKeyEnabled renamed to setPublisherFirstPartyIDEnabled
- tagForUnderAgeofConsent changed from method to property
- tagforChildDirectedTreatment changed from method to property

#### Steps to reproduce:

Reproduces 100% of time in my project, haven't tried to repro on Quickstart. The problem started occurring in Firebase C++ SDK 11.10.0 as I noticed it before and had to always roll back to 11.9.0 where the initialization happens with no issues. When I comment out call to `firebase::gma::SetRequestConfiguration`, the rest of the initialization and app run also goes without issues.

What happened? How can we make the problem occur?
See the code below I use for initialization, which works fine in 11.9.0

Here is log output with identifiers replaced with XXXX:
