libpldm: Add encode API for PassComponentTable request
PassComponentTable command is used to pass component information to
the firmware device. PassComponentTable command contain component
information table for a specific component including
ComponentClassificationIndex, ComponentClassification, and version
details. This implementation works with DSP0267_1.1.0, DSP0267_1.0.1
and DSP0267_1.0.0.
Tested: Unit tests passed
