User: Make the user_login field readonly instead of disabled.

On the profile edit screen in ``wp-admin, the username was previously displayed using an input field with the `disabled` attribute. This field was skipped by screen readers, which leads to a loss of information for visually impaired users. This changeset switches it to a `readonly` attribute, which is exactly the purpose of this field.

Fixes #60774.
