efi: Add support for UEFIv2.5 Properties table

Browse Source 
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.
