Subject: [PATCH 1/3] Add Chassis State Transition interface

This adds the Chassis State Transition interface in preparation
to support the mapping defined in the design document below.

ref: https://gerrit.openbmc-project.xyz/c/openbmc/docs/+/22358

Tested:
Ran each IPMI chassis control command to confirm the expected
behavior:
ipmitool power on: system is powered-on
ipmitool power off: system is forced off
ipmitool power cycle: system is forced off then powered-on
ipmitool power reset: system is hard reset
ipmitool power soft: soft power-off requested from system software
