1. Update DxeIpl PEIM to not use PeCoffLoaderLib to load DXE core. Instead, we choose to use EFI_PEI_LOAD_FILE_PPI to load DxeCore. This implementation can help to save ~3KB size for PEI phase.

2. Update DxeIpl PEIM to not use S3Lib and RecoveryLib since the dependent PPIs have been moved from IntelFrameworkPkg to MdePkg. This will help to reduce the library instance selection in platform DSC files.
