I don't think it's elegant to change FetchResponse from a class that used to always resolve a promise when it's done to a class that either resolves a promise when it's done or calls a lambda.  I think instead we should make it a class that always calls a lambda when it's done and the lambda would resolve a promise in the cases where it should, or we should take a Variant<FetchPromise, EndOfLoadCallback> to make it clear that it does one or the other, then make better abstractions for what it is supposed to do when it's done.

The two lambdas will be useful for the same fetch response in the future.
I will change the promise into a lambda and add a setter for EndOfLoadCallback.

We're just moving this code to use it below?  We already kind of have this in SharedBufferDataReference.  This should be united with that, and maybe that should be cleaned up.

Didn't know about SharedBufferDataReference.
Code is moved and refreshed a bit.
It also fixes a potential bug when trying to encode a SharedBuffer whose size is 0.

But then, we should only set responseBody if buffer is not null here...

We should probably get rid of it.
