IntelFsp2WrapperPkg: Add support to handle ResetRequired return Status from FSP.
As per FSP 2.0 spec, FSP shall not trigger system reset and instead it
shall return from the FSP API to the BL/Wrapper with the required reset
type. The changes are to handle the ResetRequired return code from FSP
APIs and provide lib interface for platform to trigger the actual reset.
