migration: cpr-exec-command parameter

Create the cpr-exec-command migration parameter, defined as a list of
strings.  It will be used for cpr-exec migration mode in a subsequent
patch, and contains forward references to cpr-exec mode in the qapi
doc.

No functional change, except that cpr-exec-command is shown by the
'info migrate' command.
