overload PrintTo for std::type_info and std::type_index
Included the string returned by their `name()` member function with the output of `PrintTo`.
Typical use case:
std::unique_ptr<AbstractProduct> product = FactoryMethod();
// Assert that the product is of type X:
ASSERT_EQ(std::type_index{typeid(*product)},
std::type_index{typeid(ProductX)});
Possible output in case of a test assert failure, now including the names of the compared type indices:
> error: Expected equality of these values:
> std::type_index(typeid(*product))
> Which is: 8-byte object <D0-65 54-8C F6-7F 00-00> ("class ProductY")
> std::type_index(typeid(ProductX))
> Which is: 8-byte object <40-64 54-8C F6-7F 00-00> ("class ProductX")
With help from Krystian Kuzniarek.
