Form Prefill restores default values for emtpy fields on form submit failure

Bug present as of version: 2.24.7-SNAPSHOT

When a form submission fails, the Form Options field generally restores the options to what was submitted by the user. So if I have checkboxes submitted as:

[x] One [x] Two [ ] Three

On submit fail the values are restored to:

[x] One [x] Two [ ] Three

If one of the options is set to `Selected` as default by the field dialog the above still works **unless** the user submitted the form with all fields unchecked. So let's say "Three" is "Selected" by default.

User unchecks "Three" and submits

[ ] One [ ] Two [ ] Three

On failed submission, the form option is incorrectly reset to

[ ] One [ ] Two [x] Three

This issue also affects the Text field. This issue (default value restored for an empty submitted value) is not the same as https://github.com/adobe/aem-core-wcm-components/issues/2805 where Text field is giving priority to the default value over a non-empty submitted value.

Reproduce the failed-submit behavior with Form Options checkboxes whose default is Selected, then repeat it with an empty Text field. Compare the behavior with issue #2805 and trace the form prefill handling for these fields; done means submitted empty values remain empty after a failed submission instead of restoring defaults.
