refactor(build): update CMake configurations and toolchain for macOS

- Modified CMake settings to ensure consistent use of the Homebrew LLVM/Clang installation on macOS.
- Added a new toolchain file to specify the correct compiler and header search paths, resolving potential conflicts.
- Updated CMake presets to enable the EMU build and set appropriate compiler flags.

Benefits:
- Enhances build reliability and compatibility on macOS by utilizing the Homebrew LLVM toolchain.
- Streamlines the build process with improved configuration management.
