efi: Add support for UEFIv2.5 Properties table
Version 2.5 of the UEFI spec introduces a new configuration table called the 'EFI Properties table'. Currently, it is only used to convey whether the Memory Protection feature is enabled, which splits PE/COFF images into separate code and data memory regions.
