New JS attribute: `data-auto-leave-validation` (#7785)

Instead of a repeating pattern like: `<input type="text" value="something" data-leave-validation="something">`, you can now put a `data-auto-leave-validation="1"` attribute on a `<form>` for example, and it will automatically set the `data-leave-validation` attributes inside the form elements.

`data_auto_leave_validation(parent)`  from `extra.js` is called on slider open and page load.
