MSCV does not allow `&typeid(T)` in constexpr contexts, but the string part of the type signature can still be constexpr. In order to avoid `typeid` as long as possible, `descr` is modified to collect type information as template parameters instead of constexpr `typeid`. The actual `std::type_info` pointers are only collected in the end, as a `constexpr` (gcc/clang) or regular (MSVC) function call. Not only does it significantly reduce binary size on MSVC, gcc/clang benefit a little bit as well, since they can skip some intermediate `std::type_info*` arrays.
