[PATCH RESEND 1/5] edk2-staging/RedfishPkg: EDKII_REDFISH_PLATFORM_CONFIG_PROTOCOL

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

EDKII Redfish Platform Config Protocol defines the protocol
interfaces that abstracts the platform configuration format
and storage from EDK2 Redfish Feature driver. This protocol
provides the interfaces to get and set platform configuration
with the format and configuration storage agnostic to the
Redfish feature driver.
