CodeGen: tweak CFString section for COFF, ELF

Place the structure data into `cfstring`.  This both isolates the structures to
permit coalescing in the future (by the linker) as well as ensures that it
doesnt get marked as read-only data.  The structures themselves are not
read-only, only the string contents.
