[WIP] Fix compilation error in FunctionTraits.h for C++14

[Copilot]

Fix C++14 compilation error in FunctionTraits.h

Problem

• In C++14, noexcept is not part of the function type system
• In C++17+, noexcept became part of the function type
• Current code defines specializations for both noexcept and non-noexcept versions
• In C++14, these are the same type, causing redefinition errors

Plan

• Wrap noexcept specializations with C++17 version check (#if __cplusplus >= 201703L)
• Test compilation with C++14 standard
• Verify existing tests still pass
• Run code review and security checks

Original prompt

用户在 include\YY\Base\Functional\FunctionTraits.h 中遇到编译错误，需要处理该文件的实现，使其在 C++14 标准下可以正常编译。
