SCI: Added sanity checks for SCI3 scripts bigger than 64KB

- Extended the "verify_scripts" console command for SCI3 scripts
- Added a check for such large scripts when scripts are loaded, with
an error for now, till a mechanism to support such scripts with a
16-bit addressing scheme is in place (e.g. overlaying, or splitting
scripts). Either way, such scripts should span over more than one segment
