GoogleSignIn LLDB issues

[MartinPrusa]

Since GoogleSignIn 7.1.0 lldb Xcode started to have issues there is issue that has been solved. google/GoogleSignIn-iOS#396

We need to update to GoogleSignIn version 8.0.0, that should solve this issue

I also noticed that the size of GoogleSignIn xcframework in recent releases since rapidly shrank. Perhaps that could be issue here as well. But I believe that the path forward is to update to 8.0.0.

@MartinPrusa, that change will need to happen in the base firebase repository (when they release they should include the updated GoogleSignIn binary)
