We have `StringLiteral`s in multiple other `Carbon` sub-namespaces. Rename to a more specific name to avoid collisions. We should likely also rename `Carbon::IntId` -> `Carbon::IntValueId` and `Carbon::RealId` -> `Carbon::RealValueId`, but this collision is prioritized because it was blocking work on typed parse nodes which introduces a `Carbon::Parse::StringLiteralId`.
