PPC/s390: [builtins] Move CallApiGetter and CallApiCallback stubs to builtins 

Port 70cede39

Original Commit Message:

    Calls from embedded builtins to stubs are expensive due to the
    indirection through the builtins constants table. This moves
    CallApiGetter and the 0/1 argument case of CallApiCallback to
    builtins.
