Removes the pointer at the given index from the pointer array.
The last element in the array is used to fill in the space, so
this function does not preserve the order of the array. But it
is faster than PtrArray.stealIndex. The GDestroyNotify for array is
*not* called on the removed element; ownership is transferred to the caller
of this function.
