Track Network domain status in SessionState (#54068)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/54068

Changelog: [Internal]

Adds a `SessionState::isNetworkDomainEnabled` bit, managed in `HostAgent`, to align with other domains. Network support is still gated behind feature flags as before.
