Widget doesn't validate against field constraints

Problem/Motivation

Currently the widget ignores field-level constraints when processing entered values. As a result, values can be saved even if they don't pass constraint validators that should affect them.

Steps to reproduce

- Create your own Constraint that affects one of the fields in a given paragraph type. (You can reproduce this without coding by installing a module that provides this type of functionality, for example creating a paragraph type with an entity reference field, and then using the https://www.drupal.org/project/entity_reference_validators → to prevent duplicates on that field)
- Using the Layout Paragraphs widget, enter some content in the field that should fail validation.
- Save the form
- EXPECTED: Validation should kick-in and the form shouldn't be saved
- ACTUAL: The form is saved and no validation error is displayed

If you repeat the same operation, but this time using paragraph's own widget, the validators are applied as expected.

Proposed resolution

Call all field-level validator constraints when processing values in the widget.

Remaining tasks

Write the code, test and review.
