[PATCH 3/4] MdePkg: Add EFI_PROPERTIES_TABLE

["Oleksiy Yakovlev" <oleksiyy@ami.com>]

Define Guid & data structure for EFI_RT _PROPERTIES_TABLE, designed to be published by a
platform if it no longer  supports all EFI runtime services once ExitBootServices()
has been called by the OS.
(UEFI 2.8 errata a, mantis 2049)
