Ruiyu Ni 95fc5a8775 ShellPkg: Fix echo to support displaying special characters
Run 'echo -t' without the patch will get the result:
  echo: Unknown flag - '-t'
  The expected result is to display '-t' literally.
  This patch adds special handle for 'echo'. 'echo' will not use the
  general parameter parsing library.
