[Platform] Fix Matter framework delegates to pass the delegating object as the first arg to their methods

[bzbarsky-apple]

Reproduction steps

The API design advice is:

Pass the delegating object as the first argument.

That said, it's not really clear to me which of our objects are "delegates" in that sense. For example, the MTRKeypair protocol really doesn't seem to fit into the "need to know the delegating object" bucket. Does the storage protocol?

Part of #22420. May have some interactions with #22542 and #22594 which rename things. And #22537 which might fix this for the pairing delegate.
