Fix #22984

The array and apache Map decoders never registered the node being decoded, unlike to_zval_object_ex(), so a child href or enc:ref pointing back at an enclosing array recursed until the native stack was exhausted. An empty holder is now registered before the children are converted, and replaced by the completed value afterwards.
