Reland "Change GN to disallow reading args defined in the same..."

This re-lands r433944, "Change GN to disallow reading args defined in
the same declare_args() call." The change was reverted in r439366 when
we though it might be the cause of some flakiness, but that turned out
to be wrong (the change was fine).
