feature(config-utl): enables webpack configurations in ESM format BREAKING

[sverweij]

Description

• uses import instead of require for webpack configurations that look like they can be loaded natively.
• still uses the require hack with rechoir/ interpret for configurations that look different.

This makes the config util that loads webpack configurations asynchronous which is 🚨 BREAKING.

Motivation and Context

• to remain consistent with the formats we support for babel and dependency-cruiser itself.
• because it's possible now.

How Has This Been Tested?

• green ci
• updated automated integration tests
