Support using underlying input channels audience as Sequences audience

[creydr]

As the Eventing OIDC feature track describes, Addressables (and thus Sequences) need to announce their audience in .status.address.audience. As an implementation detail, a Sequences address points to a Channel (which is an Addressable too and thus has an Audience). Therefor an Sequences audience should be equals to its input channels Audience.

In particular the Sequence controller should:

• Set the Sequences Audience (.status.address.audience) to the same value as its input channels Audience (.status.address.audience)

Additional Information:

• requires Support exposing the Audience of an InMemoryChannel #7187
