Emit event declared in (non inherited) interfaces

[Amxx]

Abstract

Allow a library, or a contract, to emit an event declared in a interface using the following syntax

emit I.EventName();

Motivation

Since 0.8.20, if a libraries emits an event, the contract that uses the library should include the event in its ABI

#10996 includes the following test:

library L {
    event e1(uint b);
}

function f() {
    emit L.e1(5);
}

contract C /* is L ? */ {
    event e1(uint indexed a);
    function g() public {
        f();
    }
}

However, one may want to use events from an interface rather then defining them in a library

interface I {
    event e1(uint b);
}

library L {
    function f() internal {
        emit I.e1(5);
    }
}

contract C {
    event e1(uint indexed a);
    function g() public {
        L.f();
    }
}

Unfortunatelly, this is not accepted:

TypeError: Member "e1" not found or not visible after argument-dependent lookup in type(contract I).

Backwards Compatibility

I don't see any backward compatibility issue.
