Cover cxxreact:bridge with Stable API guards (#58404)

Summary:
Pull Request resolved: #58404

Classifies `cxxreact:bridge` as a private target under the three-tier C++ stable API visibility model. Consumers that opt into `RN_STRICT_API` now get an error if they include its headers directly; without that flag the guards are inert, so no existing build changes behaviour. `ReactNativeVersion.h` is a generated file, so its guard also goes into `scripts/releases/templates/ReactNativeVersion.h-template.js`; without that the next version stamp would rewrite the header and silently drop the guard from every release and nightly artifact.
