Adds new partial scope stacks to the partial path arena. count is the number of partial scope stacks you want to create. The content of each partial scope stack comes from three arrays. The lengths array must have count elements, and provides the number of scopes in each scope stack. The scopes array contains the contents of each of these scope stacks in one contiguous array. Its length must be the sum of all of the counts in the lengths array. The variables array must have count elements, and provides the optional scope stack variable for each partial scope stack.

You must also provide an out array, which must also have room for count elements. We will fill this array in with the sg_partial_scope_stack instances for each partial scope stack that is created.
