This commit does the following
- Implements the GetPLDMTypes and GetPLDMCommands commands. These are
  commands that need to be handled by a PLDM device as part of the
  initial PLDM discovery.
- Sets up the build infrastructure: separate libraries for PLDM
  encode/decode libs and the PLDM responder.

The libpldm is written in C and can be shared with projects other than
OpenBMC. The code written in C follows the Linux kernel coding guidelines.
The libpldmresponder and the application code follows the modern C++ and the
clang format follows the OpenBMC coding guidelines.

clang-format for each input file will try to find the .clang-format file
located in the closest parent directory of the input file. Since the C code is
in libpldm directory it has a specific .clang-format.
