[extension_google_sign_in_as_googleapis_auth][google_maps_flutter_ios] Manual roll with fixes to example and skipping some native tests (#7571)

It looks like flutter/packages#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
