Support withdrawal for multiple entities in a single transaction

[zajck]

A wallet can control multiple accounts at once if they are of different types (buyer, seller, dispute resolver, agent, royalty recipient).

Funds for these accounts are tracked individually, so if a user wants to withdraw them, they must call withdrawFunds for every entity they control.

To make it more user friendly, we could change withdrawFunds to accept array of entity ids (uint256[] calldata _entityId) instead of a single value and withdraw all funds in a single transaction.
