Add setting to display flag or country code in the Country field

I've developed a patch to hide the flag linked to the phone number field. With this patch, no additional configurations are required.

I've noticed an additional requirement. According to your specifications, a configuration field is needed to control the visibility of the flag icon. Accordingly, I've created a patch that allows for the convenient hiding or displaying of the flag icon. To hide the flag icon, you can enable the "Disable Flag field" option in the phone element.

Commit in #15 improves upon the previous version in several ways.

1. Just hiding flag creates ambiguous situation for calling code +1 which is used by multiple countries. It's not possible to know which country is actually selected by looking at the country calling code alone. To solve this issue, the new commit displays two-letter country code when the flag is hidden.

2. Previous version was incomplete, it was covering only webform element but not regular Drupal core field. New commit adds the following missing features:

• implement "Country selection" field widget setting with two options: "Flag" and "Two letter country code".
• add new setting to the field schema
• webform element: move "Country selection" setting into the Phone number settings fieldset for better usability.
• add tests for the new feature

3. This MR also includes fix for the failed phpunit test FunctionalJavascript\SelectCountryTest::testCountrySelect(). Failure was caused by a change introduced in Drupal 10.2. For details see comment #121 in Drupal core issue 📌 Stabilize FunctionalJavascript testing AJAX: add ::assertExpectedAjaxRequest() Fixed . In this particular case usage of assertWaitOnAjaxRequest() was not needed.

4. Since I was already working in this area, I also did some clean up of inefficient JavaScript code in setCountry() function.

• I chained removeClass() and addClass() methods. Previously code was doing two independent tree traversals.
• I removed unnecessary for loop that was going through all the options in Country select list in order to find the selected one. Selected option can be accessed directly without the loop.

Excellent improvements here. The current state of the MR seems to work well and does not appear to be disruptive to existing installations.
Thanks everyone!
