The UEFI spec v2.5 introduces a new memory attribute EFI_MEMORY_RO, which is now the preferred attribute to convey that the nature of the contents of such a region allows it to be mapped read-only (i.e., it contains .text and .rodata only). The specification of the existing EFI_MEMORY_WP attribute has been updated to align more closely with its common use as a cacheability attribute rather than a permission attribute. Add the #define and add the attribute to the memory map dumping routine.
