OpenPOWER: Add support for hardware dump

Hardware dump is a collection hardware state information,
including various registers, and it is used for debugging
system checkstop. checkstop is the descriptive term for
entire system termination by the hardware due to a detected error.

This commits adds
 - Hardware dump entry implementation
 - Hardware dump manager implementation

Tested:
  - Create a hardware dump
busctl --verbose call org.open_power.Dump.Manager /org/openpower/dump xyz.openbmc_project.Dump.Create CreateDump a{sv} 3  "com.ibm.Dump.Create.CreateParameters.DumpType" s "com.ibm.Dump.Create.DumpType.Hardware" "com.ibm.Dump.Create.CreateParameters.ErrorLogId" t 0xDEADBEEF "com.ibm.Dump.Create.CreateParameters.FailingUnitId" t 1
MESSAGE "o" {
        OBJECT_PATH "/xyz/openbmc_project/dump/hardware/entry/1";
};
/var/lib/phosphor-debug-collector/hardwaredump/1/hwdump_1_1627559369.tar.gz

  - Delete a hardware dump
busctl call xyz.openbmc_project.Dump.Manager /xyz/openbmc_project/dump/hardware/entry/1 xyz.openbmc_project.Object.Delete Delete

  - Offload hardware dump
  - Restore hardware dumps after restart
