Issue:
Eventing TLS: Add AddressableFromDestination method on the resolver
After https://github.com/knative/pkg/issues/2711 is implemented, as the [Eventing TLS feature track](https://docs.google.com/document/d/1H-x_oji8LqkCyd7tlsSyclmUe7FAmEJPgRxOU_0pkn8/edit) describes we should add a new method on the [resolver](https://github.com/knative/pkg/blob/main/resolver/addressable_resolver.go) as follow:

```golang
AddressableFromDestination(ctx Context, dest Destination, parent interface{}) (*Addressable, error)
```

The implementation should be similar to `URIFromDestination`

https://github.com/knative/pkg/blob/main/resolver/addressable_resolver.go#L75-L76C10

but with the following additional algorithm/logic:

- If status.addresses of the resolved destination is set (has at least 1 element)
  - if dest.ref.address is not specified:
    - Select the first (in order) address from all addresses
    - If no address is found use status.address of the resolved destination
  -  else
     - Select the first (in order) address from all addresses with name == dest.ref.address
     - If no address is found return an error explaining that the address with name <address_value> cannot be found/resolved
- else return `status.address` of the resolved destination


Since the new `AddressableFromDestination` is a superset of `URIFromDestination`, the `URIFromDestination` should make use of the `AddressableFromDestination` method but return the  resolved URI
