The assumption here is that decomposed characters render like their
composed character equivalents, and that working with the former
comes with a risk of over-estimating string widths given that
we compute them on a per-code-point basis. The regression test
added here (한글 vs 한글) is an example of that happening.

Inspecting errors results in duplicated information in case an error

This is only active if the `showHidden` option is truthy.
The implementation is a trade-off between accuracy and performance.
This will miss properties such as properties added to built-in data
types.
The goal is mainly to visualize prototype getters and setters such as:
class Foo {
ownProperty = true
get bar() {
return 'Hello world!'
}
}
const a = new Foo()
The `bar` property is a non-enumerable property on the prototype while
`ownProperty` will be set directly on the created instance.
The output is similar to the one of Chromium when inspecting objects
closer. The output from Firefox is difficult to compare, since it's
always a structured interactive output and was therefore not taken
into account.

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.
