[roll] Roll fuchsia [fxfs][unicode] Add CasefoldStr

This adds a `CasefoldStr` which is to `CasefoldString` what `str` is
to `String`. I also removed what I consider a bit of a foot-gun where
we can elide a case-insensitive CasefoldString to a case-sensitive str
via dereference.

Will be using these in DirentEntry refactoring change shortly.
