Formalize an API for programmatically updating prop values

I believe you meant to use this issue queue component?

100% @wim leers, Thanks. 🙏

@wim leers That's my fault, thanks for fixing it!

MR 3538576-stage-1-split-input-behaviors makes no functionality changes - it's just splitting inputBehaviors so the form-specific parts are in dedicated files. It should make the next step easier to review, so perhaps that can get in quickly and we'll focus on the next functionality-impacting MR.

Got a +1 from @hooroomoo to merge the 3538576-stage-1-split-input-behaviors branch. With that in, the MR that actually implements the requested functionality should be easier to review. (it will definitely be easier to implement)

bnjmnm → changed the visibility of the branch 3538576-programatically-update-model-values to hidden.
