Synchronize the API with Omni Token.

[olga24912]

Omni Token: https://github.com/Near-One/omni-bridge/blob/main/near/omni-token/src/lib.rs

It is planned to use the Bridge Token in Omni Bridge. To make this possible:

1. Added a function that sets a new controller in tokens. For the controller to be updated, confirmation from the new controller is required.
2. Changed the API for mint. Now, ft_transfer_call is executed inside mint to be compatible with the functionality in OmniToken.
3. Added the sender_id field to finish_withdraw to support a similar interface in OmniBridge without changing the token functionality related to the withdraw call.
