Cover react/renderer/consistency:consistency with Stable API guards (#58046)

Classifies `react/renderer/consistency:consistency` as a private target under the C++ stable API three-tier visibility model. Adds `#include <react/cxxstableapi/PrivateGuard.h>` to both headers in the module and declares the guard dependency in BUCK, CMake and the podspec.
