fix: use lldb when debugging with C++ extension on MacOS

See https://github.com/rust-lang/rust-analyzer/issues/16901#issuecomment-2024486941

This PR resolves the issue of being unable to debug using the C++ extension on macOS. By using special configurations for the `MIMode` on macOS, it enables the C++ extension to connect to lldb when debugging (without affecting other platforms).
