Properly setup headers for FBReactNativeSpec in prebuilds (#52783)

Summary:
bypass-github-export-checks
Pull Request resolved: #52783

This change reverts D78158734 which was a patch to make the dynamic frameworks work properly because we were not exporting the FBReactNativeSpec headers in prebuilds correctly.

This change fixes this, by exposritng those headers correctly.
