refactor: reorderOptions support subcommands

[CodingPoeta]

• keep reorder options for all flags
• if HelpFlag is set, it will be moved after the last command's flags
• allow subcommands with flags
• if deeper subcommand's flags overlap with it's ancestors, it have higher priority to catch the flag
