Make consider-using-augmented-assign an extension

[DanielNoord]

I haven't followed the discussion around this check so it might have come up already.

Why was this not implemented as an optional extension?

From what I can tell there is no obvious benefit to using the augmented assignment over the regular one. IMO it just creates a lot of unnecessary noise. Similar checks like the one for assignment expressions are also optional.

@cdce8p should this be in CodeStyle? Or just a full extension?

consider-using-tuple and consider-using-assignment-expr are part of the CodeStyle extension, too. So I think there is an argument for it here.

A bit off-topic, I think it would be awesome if we could disable all CodeStyle checks by default so that users can / must choose which ones they want to enable. Haven't checked if that's already possible.

Agreed.

Agree with you @cdce8p, we're delaying #3512 but it's one of the most important issue to fix at this point.
