libpldmresponder: bios: Add SetDataTime

Implement the time setting function based on decode requests,
set values and return responses.
It contains the error response.
Unit tests only include tests for numerical conversion.

Tested:
 ~# pldmtool bios SetDateTime -d 20200101080000
 Encode request successfully
 Request Message:
 08 01 80 03 0d 00 00 08 01 01 20 20
 On first recv(),response == request : RC = 0
 Total length: 6
 Shutdown Socket successful :  RC = 0
 Response Message:
 08 01 00 03 0d 00
 Set date time successfully.

 ~# busctl get-property xyz.openbmc_project.Time.Manager\
 /xyz/openbmc_project/time/host\
 xyz.openbmc_project.Time.EpochTime Elapsed

 t 1577865726549597

The value of epochtime matches the time entered.
