libpldm: Add decode API for GetFirmwareParameters response
decode_get_firmware_parameters_resp_comp_set_info decodes the
GetFirmwareParameters response except the component parameter table.
Update agent sends GetFirmwareParameters command to acquire the
component details such as classification types and corresponding
versions of firmware device. Its defined in DSP0267 Version 1.1.0
sec:10.2.
Tested: Unit tests passed
