Was always broken for pipes created by Windows' shells (PowerShell and Command).
Became broken in cygwin 3.4.x for pipes created by cygwin/MSYS2/Git for Windows
shells when cygwin started mimicing the way Windows shells create pipes. The cause
is that setting the `FILE_SYNCHRONOUS_IO_NONALERT` option when creating a
pipe causes `cin.seekg(0)` on the pipe to return success when in fact seek is not
supported.

* Add launchDebugger function and --ld option to invoke it to `ktxApp` class and ktx tool
   as helpers for debugging pipes on Windows. These are only added when _WIN32 and
   DEBUG are defined.
