Compiles with llvm 17. Solves #98.

[HFTrader]

There is a single change in ABI that breaks compiling with clang-17: LLVMModule::getGlobalList() to LLVMModule::globals(). That was wrapped with an #if

A second change is to match any provided LLVM version in find_package() and use a second check to match major versions from 16 to 17. The reason for this is that even though we can provide a version range in find_package(), the LLVMConfigVersion.cmake installed with the llvm distribution will only match exactly the MAJOR.MINOR version.

Big thank you for preparing and sending this 🙏🏻

In general, I try to keep llvm-tutor based on the latest release (that simplifies a lot of things), but LLVM 17 isn't out yet. This change will simplify the transition once the release happens.

LGTM
