Cygwin: console: Retain ENABLE_VIRTUAL_TERMIANL_PROCESSING flag.

Browse Source 
- 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.
