Make signature support IDA/x64Dbg style

[Nukoooo]

See discussion for more info.

TLDR: Make developers' life easier so they don't have to convert their signatures(48 8B ?) to code style(\x48\x8B\x2A) every time when they make a signature

What's changed

• Signature now supports IDA/x64Dbg style (48 8B ? ? ? ? ?)
• Removed duplicated code
• Switched to C++20 (because of std::views::split)
• FindSignature now uses std::find and std::equal for better readability

LGTM, what platforms have you tested this on?

I only tested on Windows. but I also tried to compile with GCC 13.2.1 and Clang 17.0.6 on my Arch WSL, while GCC ccompiled successfully without any error, clang required to remove register keywords in hl2sdk-cs2/tier1/generichash.cpp to make it work

Just took a look at why the build failed on linux, it turned out std::string_view(split.begin(), split.end()) only exists in GCC 12.1 and above and Clang 16.0.0 and above see here. So it might need to upgrade the compiler that workflow uses newer compiler.

Tested on Linux using latest build artifact ✅
