Include additional error properties from nested error causes

[fungairino]

As a follow-up to #2569, it would be very helpful if each error in the cause chain was logged with all of their additional properties (rather than just the message, source, type and stack)

This would be very helpful for us in cases where we want to include additional debugging information in an error we are throwing in a deep context which is then embedded as a cause and reported to datadog. We have had to work around this by just including it in the error message for now. See: https://github.com/pixiebrix/pixiebrix-extension/pull/9262/files

For reference this was the change to support error causes:
