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

See #16901 (comment)

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).
