prov-mode-mgr: Log events for restriction mode

Support added to log events for restriction mode change (system
interface), which can be viewed using Redfish event log entries.
This log will indicate the status of the system interface command
execution allowed state after BIOS POST.

Tested:
Tested the same with up-stream message entry review
https://gerrit.openbmc-project.xyz/#/c/openbmc/bmcweb/+/26601/
1. Redfish validator - passed for this new addition
2. Log will be as below
