`<typeinfo>`: `type_info`'s True Name should be in `std`, but is in the global namespace

Reported by @frederick-vs-ja in https://github.com/microsoft/STL/issues/2195#issuecomment-917427326 :

This issue should belong to vcruntime (but may belong to this repo later).

BTW, in the MSVC implementation, the class type_info is originally defined in the global namespace, which brings some non-conforming result. E.g., the following code should be rejected because range-for does ADL-only lookup, but is accepted by MSVC:

#include <typeinfo>

inline int *begin(std::type_info const&) { return nullptr; }
inline int *end(std::type_info const&) { return nullptr; }

int main()
{
    for (auto i : typeid(void));
}

vNext note: Resolving this issue will require breaking binary compatibility. We won't be able to accept pull requests for this issue until the vNext branch is available. See #169 for more information.

Begin with the issue's C++ example and the note that the problem may belong to vcruntime. Review #169 and wait for the vNext branch, since resolving this requires breaking binary compatibility and pull requests are not currently accepted. Done means making std::type_info's true name conform to the standard and rejecting the demonstrated ADL-only range-for case.
