MdeModulePkg: Add PcdTdxSharedBitMask
RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3429
Guest Physical Address (GPA) space in Td guest is divided into private
and shared sub-spaces, determined by the SHARED bit of GPA. This PCD
holds the shared bit mask. Its default value is 0 and it will be set
in PlatformPei driver if it is of Td guest.
