[#505] ir/container: Implement simplified handling of SetEACL event

Implement `handleSetEACL` method similar to other handling methods in
Container processor. To begin with, the validation logic is skipped, and all
tables will be sent to the contract. In the future, the necessary checks
will be implemented. Listening for events in the IR node will also be added.
