Summary: Pull Request resolved: https://github.com/facebook/react-native/pull/43098 Changelog: [Internal] Wraps Hermes's `CDPHandler::getState()` API in an engine-agnostic abstraction (`RuntimeAgentDelegate::getExportedState`). An Agent's lifetime ends when its Target is destroyed, but it can occasionally be useful to persist some state for the "next" Target+Agent of the same type (in the same session) to read. `RuntimeAgentDelegate` is polymorphic and can't just write arbitrary data to SessionState. Instead, it can now *export* a state object that we'll store and pass to the next `RuntimeTargetDelegate::createAgentDelegate` call.
