[reflection][feat]support non aggregate

[qicosmos]

Why

support reflect non-aggregate type with YLT_REFL.

What is changing

Example

struct simple2 {
  int color;
  int id;
  std::string str;
  int age;
  simple2() = default;
  simple2(int a, int b, std::string c, int d)
      : color(a), id(b), str(c), age(d) {}
};
YLT_REFL(simple2, color, id, str, age);


int main() {
  simple2 t{2, 10, "hello reflection", 6};

  visit_members(t, [](auto&... args) {
    CHECK(sizeof...(args) == 3);
    ((std::cout << args << ", "), ...);
    std::cout << "\n";
  });

  for_each(t, [](auto& arg) {
    std::cout << arg << "\n";
  });

  auto& age1 = get<int>(t, "age");
  CHECK(age1 == 6);

  auto str2 = get<2>(t);
  CHECK(str2 == "hello reflection");

  auto var = get(t, 3);
  CHECK(*std::get<3>(var) == 6);

  auto& age2 = get<"age"_ylts>(t);
  CHECK(age2 == 6);

  auto& var1 = get<"str"_ylts>(t);
  CHECK(var1 == "hello reflection");

  constexpr size_t idx = index_of<simple2, "str"_ylts>();
  CHECK(idx == 2);

  constexpr size_t idx2 = index_of<simple2, "no_such"_ylts>();
  CHECK(idx2 == 4);

  constexpr std::string_view name1 = name_of<simple2, 2>();
  CHECK(name1 == "hello reflection");

  constexpr std::string_view name2 = name_of<simple2>(2);
  CHECK(name2 == "hello reflection");
}
