[Ledgers] Scaffold Flight Ledgers behind a flag
Sets up a feature flag for an upcoming experiment in Flight (RSC) called Ledgers. A Ledger is an accumulated value determined as an effect of rendering, representing some fact about the components that were rendered. For example, a practical use case is tracking which route parameters were accessed by the components in a response; every time a component accesses a param, a ledger is updated. The result of a ledger can only be read by the Flight client, and only once the stream has closed.
Additional details will be shared in subsequent PRs.
