Add additional Redfish Processor properties

This commit adds the following inventory properties for the
Processor resource in bmcweb:

a) LocationCode, a free form, implementation-defined string
to provide the location of the processor. This is needed so an
implementation can identify the processor via system diagrams.

b) SparePartNumber, also field-replaceable unit (FRU) Part
Number, is a part number that identifies the FRU for replacement
specifically ordering of a new part.

c) PartNumber, also called a Marketing Number, describes a
specific part within a specific system among a manufactures various
product lines. These numbers tell IT infrastructure technicians
exactly which parts are included in their servers, storage and
networking equipment.

These properties are essential to locate and replace the FRU.

Validator has been executed and no new error has been found.

Sample Output:
