Subject: fix: allow preventing SetPromiseRejectCallback
We do not want to use the promise rejection callback that Node.js uses,
because it does not send PromiseRejectionEvents to the global script context.
We need to use the one Blink already provides, and so we need to
slightly augment IsolateSettings to allow for that.
