[EFI Redfish Host Interface PATCH v2 4/6] RedfishPkg/RedfishHostInterfaceDxe: Create SMBIOS type 42 record

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

This is the abstract driver to consume the contents of SMBIOS type 42h
device descriptor and protocol type data which provided by
PlatformHostInterfaceLib, and create SMBIOS type 42 record through
EFI SMBIOS protocol.
