Try to dispatch a parsed `NodedbStatement`. Returns `Some` if fully handled, `None` if the statement should fall through to the legacy dispatch.

    state: &SharedState,
    identity: &AuthenticatedIdentity,
    stmt: &NodedbStatement,
    database_id: DatabaseId,
)

/// fully handled, `None` if the statement should fall through to
