Hermès Bélusca-Maïto d78e8029b8 [CMD] Additional fixes for ERRORLEVEL and last returned exit code from EXIT, CALL commands and CMD. ...

CORE-10495 CORE-13672

- Fix how the ERRORLEVEL and the last returned exit code are set by
  EXIT and CALL commands, when batch contexts terminate, and when CMD
  runs in single-command mode (with /C).

  Addendum to commit 26ff2c8e, and reverts commit 7bd33ac4.
  See also commit 8cf11060 (r40474).

- Move the actual execution of the CMD command-line (in /C or /K
  single-command mode) from Initialize() to _tmain(), to put it on par
  with the ProcessInput() interactive mode.

- Make ProcessInput() also return the last command's exit code.
