Create script to automatically set CLANG_CXX_LANGUAGE_STANDARD on the client project (#33863)

Browse Source 
Summary:
Currently this [section](https://reactnative.dev/docs/next/new-architecture-app-intro#ios-enable-c17-language-feature-support) of the Playbook tells us to set CLANG_CXX_LANGUAGE_STANDARD = "c++17" in the main app target for the new architecture to work.
Would be nice to be able to automate that instead

Test Plan:
I've created some unit tests for the newly added function.
I've executed pod install and the ruby tests locally.
