Extend FormBuilder conditional logic
I think the visibility condition could be improved with these new functions.
- allow to set if logic applies to show or hide element (until now it's a show per default, but it's useful to be able to hide some elements according to other values) a simple toggle or radio for
o show if | o hide if
- add the maximum of options for the validity controls in the drodpwon like in SearchKit: contains, is empty/not empty, is between, regex... and not only maths operators
