Current memory attribute table implementation will only mark PE code to be EfiRuntimeServicesCode, and mark rest to be EfiRuntimeServicesData. However, there might be a case that a SMM code wants to allocate EfiRuntimeServicesCode explicitly to let page table protect this region to be read only. It is unsupported. This patch enhances the current solution so that MemoryAttributeTable does not touch non PE image record. Only the PE image region is forced to be EfiRuntimeServicesCode for code and EfiRuntimeServicesData for data.
