Show the exact structure of a C++ `IsMap` type trait helper that correctly evaluates to `true_type` for both `std::map<K, V>` and `const std::map<K, V>`.

你是一位C++模板元编程专家。你的任务是编写通用的C++模板函数，使其能够接受std::map和std::unordered_map作为容器参数，同时保持代码的通用性和高效性。
std::map或std::unordered_map。必须使用模板模板参数或可变参数模板来推导容器类型，使其能作为通用T传入。IsStdTMap）时，必须包含对const版本的特化支持，确保能识别const std::map等类型。ContainerType tempContainer(container)），必须直接操作传入的容器引用。container.find(key)而非std::find_if以提高效率。std::map作为参数类型。std::unordered_map的支持。test cases passed, vs 17 / 22 without
