Upgrade UIManager visibility to "for frameworks"

Summary:
Reclassifies `react/renderer/uimanager:uimanager` from public to "for frameworks" under the C++ stable API three-tier visibility model.

Consumers that opt into `RN_STRICT_API` now get a suppressible warning where they previously got an error pointing at the umbrella, and can acknowledge it with `RN_ALLOW_FRAMEWORKS`; without that flag the guards are inert, so no existing build changes behaviour.
