Change PostCode property signature

- This commit would change the backend signature of the
  PostCode Raw Value property.

- IBM progress codes are typically around 72 bytes including a
  primary code (typically 8 bytes) & a secondary code that
  contains hex words that would provide additional details on the
  core problem during boot hangs.

- The intent behind this commit is to change the signature of the
  backend Post Code Raw Value Property as per the proposed PDI
  change.

- This commit has various dependencies across mutiple repos like
  phosphor-host-postd, phosphor-post-code-manager, all the dependent
  commit can be found in gerrit with topic name : progress codes

Tested By :
1. PATCHED a witherspoon system with the new PDI library with both
   changes(40927,40936).
2. PACTHED the new snoopd daemon, post code manager, bmcweb & pldm with
   the progress code support.
3. Trigger a progress code(ASCII Value : STANDBY) using the pldm tool as shown below:

./pldmtool raw --data 0x80 0x3F 0xC 0x0A 0x00 0x00 0x00 0x00 0x00 0x07
0x00 0x00 0x00 0x48 0x00 0x00 0x00 0x02 0x00 0x00 0x01 0x00 0x00 0x00
0x48 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00
0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00
0x00 0x00 0x00 0x00 0x00 0x53 0x54 0x41 0x4e 0x44 0x42 0x59 0x20 0x20
0x20 0x20 0x20 0x20 0x20 0x20 0x20 0x20 0x20 0x20 0x20 0x20 0x20 0x20
0x20 0x20 0x20 0x20 0x20 0x20 0x20 0x20 0x20

4. Now check the Raw Property :
busctl call xyz.openbmc_project.State.Boot.Raw /xyz/openbmc_project/state/boot/raw0
org.freedesktop.DBus.Properties Get ss xyz.openbmc_project.State.Boot.Raw Value
v (tay) 6004496007600167200 72 2 0 0 1 0 0 0 72 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0 0 0 0 0 83 84 65 78 68 66 89 32 32 32 32 32 32 32 32 32 32 32 32
32 32 32 32 32 32 32 32 32 32 32 32 32

5. Check the Redfish GET on Post Code Log Service Entry

{
  "@odata.id": "/redfish/v1/Systems/system/LogServices/PostCodes/Entries",
  "@odata.type": "#LogEntryCollection.LogEntryCollection",
  "Description": "Collection of POST Code Log Entries",
  "Members": [
    {
      "@odata.id": "/redfish/v1/Systems/system/LogServices/PostCodes/Entries/B1-1",
      "@odata.type": "#LogEntry.v1_4_0.LogEntry",
      "Created": "2021-02-27T08:38:31+00:00",
      "EntryType": "Event",
      "Id": "B1-1",
      "Message": "Boot Count: 1: TS Offset: 0.0000; POST Code: 0x5354414e44425920",
      "MessageArgs": [
        "1",
        "0.0000",
        "0x5354414e44425920"
      ],
      "MessageId": "OpenBMC.0.1.BIOSPOSTCode",
      "Name": "POST Code Log Entry",
      "Severity": "OK"
    }
  ],
  "Members@odata.count": 1,
  "Members@odata.nextLink": "/redfish/v1/Systems/system/LogServices/PostCodes/Entries?$skip=1000",
  "Name": "BIOS POST Code Log Entries"
}

The post code Field shows 0x5354414e44425920 in Hex(In Ascii it would be
STANDBY)
