oem/libpldm: platform: implement responder flow for GetAlertStatus
For the responder, need to encode responder data and send requester,
waiting for recive requester data to decode, so need to implement
encode/decode(Responder flow only) for GetAlertStatus.
The GetAlertStatus is a custom oem command to report enclosure ids of
system, alert status and flags, and config ID.
Request Data:
Type - Request Data
uint8 - Version of the command/response format. 0x0 for this format.
Response Data:
Type - Response Data
enum8 - completionCode.value{PLDM_BASE_CODES, UNSUPPORTED_FORMAT_VERSION=0x81}
uint32 - Enclosure ID, AlertStatus, Flags, Config ID.(rack entry)
uint32 - Enclosure ID, AlertStatus, Flags, Config ID.(pri cec node)
