Partially fix compatibility with Visual Studio 2019

[chenxiaolong]

This adds a missing <codecvt> include and switches switches from auto_ptr to unique_ptr.

This doesn't completely allow the project to be built with VS2019. ldid also needs to target C++17 and use std::filesystem instead of std::experimental::filesystem. I didn't include this change in the PR because I'm not sure if it'll break compilation with earlier versions of MSVC.

Sir, can you please share build instructions? I am very stuck

@rileytestut Do you use VS 2019 to compile AltServer for Windows? Is this worth looking into - someone did approve it on Feb 2nd of this year.

Imma just close it for now since this conflicts anyway now.
