[extension_google_sign_in_as_googleapis_auth][google_maps_flutter_ios] Manual roll with fixes to example and skipping some native tests

[bparrishMines]

It looks like #7521 missed a few packages examples and they are now failing to compile on main.

Some native tests have also began to fail consistently for google_maps_flutter_ios: flutter/flutter#154641

Some legacy iOS webview_flutter tests were also failing: flutter/flutter#154676
