add doNotBelongToAnyOf(..) to syntax

[perlun]

We have belongToAnyOf(), but the inverted form (doesNotBelongToAnyOf()) is missing and I couldn't find any easy way to just invert this in my ArchUnit invocations, so I concluded that perhaps it would make sense to add this to the framework proper?

The Javadocs are not really that great; feel free to suggest alternative wordings there. To the best of my knowledge, all tests should succeed including the tests for the functionality being added here.

Thanks a lot for helping with this! And please excuse me, that it took me such a long time to look into your PR 😞
It all looks very good, I just have one suggestion regarding your additional DoesNotBelongToAnyOfPredicate. I think we can simply negate the existing predicate using the standard ArchUnit predicates "toolbox"
I added a simple review commit to demonstrate this. Does this look good to you? If yes, feel free to squash my commit onto yours and force push to have one neat commit for eternity 😉

Did you get a chance to look into this?

Ah, sorry for the delay. Will try to get this sorted now.

@codecholeric Squashed into one nice little commit now, should be up for final review. Again, sorry for the unnecessary delay from my part on this one. 🙈

No worries, it took me long enough to review your stuff, I'm certainly not gonna bitch if you need a little time 😂 I guess there are still some tests failing, but I'll fix them up and merge this then 👍
Thanks again for your contribution 😃 I really appreciate it!!
