)Delegates voting power from account to delegatee.
To reclaim voting power (i.e. "undelegate"), call this with
delegatee set to account (self-delegation). There is no
separate undelegate operation.
e - Access to the Soroban environment.account - The account delegating its voting power.delegatee - The account receiving the delegated voting power.topics - ["delegate_changed", delegator: Address]
data - [from_delegate: Option<Address>, to_delegate: Address]
topics - ["delegate_votes_changed", delegate: Address]
data - [previous_votes: u128, new_votes: u128]
Authorization for account is required.
