Add lazy support for potential self-referential types

[nickthegroot]

Fixes #599

Schemas with self-referential types can break the generated code. Take the following example:

type Comment {
   replies: [Comment!]
}

Prior to this PR, this would create a schemas.ts file with

export function CommentSchema(): z.ZodObject<Properties<Comment>> {
  return z.object({
    __typename: z.literal('Comment').optional(),
    replies: z.array(CommentSchema()).nullish()
  })
}
// Uncaught RangeError: Maximum call stack size exceeded

This PR edits the generation code for all validation libraries to use .lazy in this case.
