Related to: #48820 and #55744

After the recursive option was added to readdir and opendir, it was noted that when specifying bufferSize alongside recursive: true, the result of opendir was incorrect. This is fixed in #55744 . However, the fix is a naive solution, and doesn't properly respect the bufferSize option. Furthermore, it could result in a blocked event loop. This should be fixed.

I recommend reading the discussion in #48820 for more information. This should only involve changes to the Dir class in lib/internal/fs/dir.js.
