[edk2-redfish-client][PATCH] RedfishClientPkg/ConvertLib: Common code and header files

["Chang, Abner" <abner.chang@amd.com>]

From: Abner Chang <abner.chang@amd.com>

ConverterLib/* is the folder of script-generated JSON
to C library for the each Redfish schema. The common
code and header files in this patch are used by those
libraries.
