Subject: [PATCH 1/2] console: use a plain object for the the error stack

Using a object instead of an Error is sufficient as the Error
itself won't be used but only the stack trace that would
otherwise be created twice.

This improves the overall .trace() performance.

Subject: [PATCH 2/2] internal/errors: prevent stack recalculation

Newer v8 versions exclude the constructor from the stack trace
so the recalculation of the trace can be avoided.
