chore: [gn] link against debug node when in debug mode (#13490)

This is required on Windows, because in Debug mode, C++ stdlib containers have a different size to when in Release mode, so the code in `node.dll` thought that `node::Environment` was a different size to the code in `electron.exe`, which uh, caused problems.

It should also make debugging through node a bit easier on all platforms.
