mysqltest, Windows - support background execution in 'exec' command

    Details

      Description

      If last character in command is ampersand, do not use my_popen/my_pclose
      in "exec", instead do CreateProcess() without a window.

      The effect of this is background execution of exec command, ampersand is chosen as to emulate to Unix shell behavior.

      Background execution had been already used in a test, which so far exclude Windows, see 10.5+ mysql-test/main/shutdown_not_windows.inc

       
      exec $MYSQL -e 'select sleep(3600)' >/dev/null 2>&1 &;
      

      There is another special case
      To test MDEV-26713, we want to start a server, with Unicode command line, and with characters outside of current ANSI codepage, e.g for the datadir . Normally, one could use MTR's "restart" functionality which would launch process via mysql-test-run.pl, i.e from Perl.
      But in this case, perl shows an i18n deficiency - Unicode would get lost/replaced with question marks.
      As a workaround for Perl deficiency, "exec $MYSQLD.. &" can be used.
