[lld-macho] Deduplicate CFStrings
`__cfstring` is a special literal section, so instead of breaking it up
at symbol boundaries, we break it up at fixed-width boundaries (since
each literal is the same size). Symbols can only occur at one of those
boundaries, so this is strictly more powerful than
`.subsections_via_symbols`.
With that in place, we then run the section through ICF.
This change is about perf-neutral when linking chromium_framework.
