Make ValidatorFactory and Validator singleton beans

[gsmet]

Created as draft to get CI feedback and because I will wait for #26997 to get in.

@gsmet I'll just add these changes as a separate commit into #26997 :)

@manovotn ah sorry, I just saw your message, I merged it as CI was green and I'm not completely sure this one will go in :). I'll adjust the small things in there.

Hehe, good timing; I was literally just pushing these changes into the PR. Doesn't matter though.

I think this change makes sense as I didn't come across any piece of code that would use Validator and somehow required that it should be dependent. If you have any further CDI questions, fire away :)

Looks good.
I don't think it is worth a backport, but I'll leave that up to you.
