IPZ VPD Parser support

This commit enables the app ibm-read-vpd to read the
IPZ format vpd. To build this app, the application
build must be configured with the "--enable-ibm-parser"
option.

The application populates the Inventory with the parsed
VPD data. The parser relies on a JSON config file
that maps the input VPD file path to the Inventory D-Bus
object that hosts the VPD data as properties.

The JSON file also supplies any additional interfaces
and properties that the D-Bus object should implement.

Argument required to run this application-
ibm-read-vpd --file vpd_file

Tested:

Also tested this on Rainier simulation model and verified that VPD
for FRUs is properly published as properties of D-Bus objects in the
Inventory.
