pldm: Convert to using libpldm transport APIs
A significant amount of logic can be removed by exploiting the new
transport APIs provided by libpldm. Switch the pldm repository over to
use these by introducing an RAII wrapper for the APIs. The current
stance is to continue using the legacy mctp-demux transport
implementation, but we also provide a build option to switch to the
AF_MCTP transport.
We don't currently have the infrastructure in place to get the correct
TIDs, so to keep everything working as before use the EID as the TID in
the EID-to-TID mapping.
