This commit implements a framework that allows describing
platform/system specific PDR information in JSON files, which the PLDM
responder library parses and builds a PDR out of.

Separate JSON files are expected per PDR type. This commit also adds the
code to build a state effecter PDR. PDR record handles are implemented
as incrementing indices, starting at 1, but this commit enables
implementing other type of record handles (for eg offset based).

This commit doesn't handle merging of PDRs received from other terminii,
so the PDR that's generated now is for the BMC. Merging of PDRs will be
implemented in future commits.

Create folder structure (oem/ibm) for ibm pldm oem commands. Move the
files from the ibm-pldm-oem repo [https://github.com/openbmc/ibm-pldm-oem

]
to the folder oem/ibm/ under the pldm repo and enable conditional
compilation for it. The test files are also conditionally compiled.

You would need to provide --enable-oem-ibm to configure.

This is done to simplify the build time and runtime dependencies between the
standard and oem implementations.

The section describing the pldm daemon was added a bit prematurely. This
is still work in progress alongwith the MCTP design. This will be
described later on once the design is finalised.
