Explicit entity signal naming?

[DasLixou]

Having an arch over an entity

entity MyEntity {
    in a: std::Logical,
}

arch RTL for MyEntity {
    AnotherComp {
        a <= a, // this is the important line
    }
}

we currently can directly name the port a from the entity.
But since it's not directly in the arch, we may consider to refer to it via self.a (a more rusty approach) or entity.a (my favorite)
