[BUG]: Email validation does not allow UTF8SMTP

[noone-silent]

Describe the bug
With the UTF8SMTP Extension, it is possible to allow any utf-8 character in the local part. Also domain names can have umlauts, but needs different parsing. RFC: https://www.rfc-editor.org/rfc/rfc5336#section-3.2

To Reproduce
Use any email, like tä[email protected]

Steps to reproduce the behavior:

            $validation = new Validation();
            $validation->add('email', new Validation\Validator\Email());
            var_dump($validation->validate(['email' => 'tä[email protected]']));

Expected behavior
Add a flag/option to allow UTF8SMTP email addresses.

When this filter is set, pass FILTER_FLAG_EMAIL_UNICODE to the filter_var function.
