Test that all collections work with zero-sized types (ZST)

[bluss]

In light of #28488, add tests to the testsuite that exercise all collections using ZST. Most common ZST is the () (empty tuple), and all collections need to support it.

I'm ok to do this :) I will jump on it today if that's alright :)

[apasel422]

@GlenDC Go for it!

[apasel422]

@GlenDC Are you still working on this?

[GlenDC]

I wasn't, but if that's fine for you I would like to retake work on this
tomorrow. I suddenly had a lot on my mind as my life will be changing a lot
from christmas on. But you revived me, so to speak. :) I will try to push a
proposed solution by tomorrow or the day after!

@GlenDC Sure, go right ahead. No rush!

I think I'll take this, since there's radio silence on this issue.

@KiChjang yes please. Sorry, for being a roadblock. Thanks for taking it over :)
