    test_paddle_save_load 单测随机挂：使用np.ndarray生成随机数组，可能生成nan，造成做对比时结果不匹配（nan != nan）。改为np.random.randn生成随机数组。

    test_paddle_save_load_binary随机挂: 如果一个字符串不能解析为Program，windows上会有超时风险。解决方法：不在windows平台不加载'不能解析为Program的字符串'。

cherry-pick #32561

Dy2stat failed when user writes return paddle.to_tensor(xxx), the reason is that visit_Expr doesn't work when the Expr is in return. Some other statements may trigger same bug. To fix it, we re-wrote a transformer to transform paddle.to_tensor to paddle.assign for all Call nodes.
