Iterator related warnings in visual studio build

Inizia da src/wasm-type.h, in corrispondenza delle definizioni degli iteratori indicate negli avvisi di Visual Studio, quindi riproduci la compilazione per individuare gli avvisi rimanenti relativi agli iteratori. Esamina le dichiarazioni degli iteratori interessati e verifica che la compilazione di Visual Studio non segnali più questi avvisi di deprecazione di C++17.

2>C:\src\binaryen\src\wasm-type.h(221,26): warning C4996: 'std::iterator<std::random_access_iterator_tag,wasm::Type,long,wasm::Type *,const wasm::Type &>': warning STL4015: The std::iterator class template (used as a base class to provide typedefs) is deprecated in C++17. (The <iterator> header is NOT deprecated.) The C++ Standard has never required user-defined iterators to derive from std::iterator. To fix this warning, stop deriving from std::iterator and start providing publicly accessible typedefs named iterator_category, value_type, difference_type, pointer, and reference. Note that value_type is required to be non-const, even for constant iterators. You can define _SILENCE_CXX17_ITERATOR_BASE_CLASS_DEPRECATION_WARNING or _SILENCE_ALL_CXX17_DEPRECATION_WARNINGS to acknowledge that you have received this warning.

And many more. Last modified here https://github.com/WebAssembly/binaryen/commit/9752196fd1357fbc129d1e4f53e8eb22cd6219f9 but it doesn't seem like the problem was introduced there.
