This change implements the account permission delegation described in XLS-75d, see https://github.com/XRPLF/XRPL-Standards/pull/257. * Introduces transaction-level and granular permissions that can be delegated to other accounts. * Adds `DelegateSet` transaction to grant specified permissions to another account. * Adds `ltDelegate` ledger object to maintain the permission list for delegating/delegated account pair. * Adds an optional `Delegate` field in common fields, allowing a delegated account to send transactions on behalf of the delegating account within the granted permission scope. The `Account` field remains the delegating account; the `Delegate` field specifies the delegated account. The transaction is signed by the delegated account.
