    Cygwin: console: Retain ENABLE_VIRTUAL_TERMIANL_PROCESSING flag.
    - Currently, ENABLE_VIRTUAL_TERMINAL_PROCESSING flag is disabled
      unconditionally when exiting from cygwin. This causes ANSI escape
      sequence disabled in Windows Terminal where it is enables by
      default. This patch retains that flag if it is originally enabled.
