Mock protocols constrained to actor types

[nathansalaun-sofia]

When I try to generate a mock to a protocol constrained to an actor, it generates a class, which is wrong. The macro should generate an actor instead.

For example:

// Input:
@Mockable
protocol SomeActor: Actor {
    var something: Bool { get set }

    func doSomething() async
}

// Generated:
#if MOCKING
final class MockSomeActor: SomeActor, MockableService {
    // ...
}
#endif

This gives the error "non-actor type 'MockSomeActor' cannot conform to the 'Actor' protocol".
