[swift-evolution] [Review] SE-0027 Expose code unit initializers on String

It arose out of the original motivation to expose and maintain the
existing methods. Users might find the `hadError` flag to be useful when
code sequence repairs are enabled. It seems like that was the original
intent, too, but everyone in the stdlib is throwing that away.

Looking at it  now, I don't think it's needed as public API. I'm in the
midst of rebasing the branch onto master, so I'll play with it on there
and update the proposal to fit.

>From an API surface area perspective, the legacy CString constructors
need the full static (not necessarily public then, of course). In a
perfect world, once those are gone, the static can get elided into the
two initializers… which makes the case even more solid for not exporting
it in this proposal.
