Introduce macro __relrodata_unpaged(x) to mark data that need to be
unpaged and are essentially read-only but may contain relocations when
ASLR is enabled, hence "relocatable read-only". When ASLR is turned off,
the macro is identical to __rodata_unpaged(x). When ASLR is on however,
the data is emitted in section .data.rel.ro.__unpaged.x which is later
gathered by the linker file into the output section .data.rel.ro which
is mapped read only at runtime (after relocations are processed) and
is also unpaged (when pager is enabled).
