Cover react/renderer/attributedstring with Stable API guards (#58305)

Summary:
Pull Request resolved: #58305

Classifies `react/renderer/attributedstring:attributedstring` as a "for frameworks" target under the three-tier C++ stable API visibility model. Consumers that opt into `RN_STRICT_API` now get a warning if they include its headers directly, which they can acknowledge with `RN_ALLOW_FRAMEWORKS`; without that flag the guards are inert, so no existing build changes behaviour.

`React-Fabric` already depended on `React-cxxstableapi` from an earlier migration in the same pod, so the module's subspec needs no change.
