[database-chassis][lagid] Initialize SYSTEM_LAG_IDS_FREE_LIST in CHASSIS_APP_DB (sonic-net#20369)

Modify database.sh to create a initial SYSTEM_LAG_IDS_FREE_LIST in the CHASSIS_APP_DB on SUP during database-chassis startup
Modify the database consistency check in swss.sh to append the lagid to the end of SYSTEM_LAG_IDS_FREE_LIST when lagid is released.
Modify the lag_id_end=1023 (not 1024) in chassisdb.conf since BCM supports the large lagid is 1023
