Previously the enhancement were done right after emitting
`'uncaughtException'`, which meant by the time we knew the
exception was fatal in C++, the error.stack had already been
patched.
This patch moves those routines to be called later during the
fatal exception handling, and split them into two stages:
before and after the inspector is notified by the invocation of
`V8Inspector::exceptionThrown`. We now expand the stack to include
additional informations about unhandled 'error' events before
the inspector is notified, but delay the highlighting of the
frames until after the inspector is notified, so that the
ANSI escape sequences won't show up in the inspector console.

This improves a couple minor things:
* Arrays that contain entries other than `number` or `bigint` are
ordered to the left instead of the right.
* The bias towards more columns got increased. That mainly increases
the number of columns for arrays that contain lots of short entries.
* Columns are now more dense in case they would otherwise have extra
whitespace in-between two columns.
* The maximum columns got increased from 10 to 15.
* The maximum number of columns per `compact` was increased from
3 to 4.

Using the `util.inspect` `compact` mode set to something else than
`true` resulted in breaking long lines in case the line would exceed
the `breakLength` option and if it contained whitespace and or new
lines.
It turned out that this behavior was less useful than originally
expected and it is now changed to only break on line breaks if the
`breakLength` option is exceeded for the inspected string. This should
be align better with the user expectation than the former behavior.

This changes the `compact` default from `true` to `3`. That mode
changes arrays to be grouped together, it alignes multiple small
entries on a single line in similar to `compact` true but only for
the most inner three depth levels and the closing brackets are
always on the same indentation as the openeing of the object instead
of at the same line as another property.
Big strings will be naturally broken into multiple lines instead of
having one huge line that is not well readable.
The output size mainly stays the same that way while it will be
smaller in case of big arrays.
Increasing the `breakLength` to 80 adjusts for most terminals that
support at least 80 characters in a single line and improves the
general output that way. A lot of calculations use the `breakLength`
