Add basic support for 'invisible' widget size

Hi,

Thanks for you're work.
I've detected a small issue when this library loads before jquery form that is mandatory to keep the originalAjaxSubmit event.
I've added a library dependency.

Sorry,

I've forgot to re-add chunk of your work on the previous message.

Hi,

When we have a submit button with the attribute #limit_validation_errors we don't want to display the hcaptcha on submit event.

Related also to that issue, https://www.drupal.org/project/drupal/issues/2895477 🐛 Native browser form validation does not fire when submit buttons use #ajax Needs work

Updated MR and refactored to not depend on core/internal.jquery.form (see change record → for deprecation).

Minimally tested, in-depth testing pending.

Patch for latest MR attached.
