tools/xenstore: add memory accounting for watches

Add the memory accounting for registered watches.

When a socket connection is destroyed, the associated watches are
removed, too. In order to keep memory accounting correct the watches
must be removed explicitly via a call of conn_delete_all_watches() from
destroy_conn().

This is part of XSA-326 / CVE-2022-42315.
