Add autocomplete attributes to fields when editing the user profile personal information

1.3.5 Identify Input Purpose
The input fields that require personal information (f.i. the fields that appear when editing the Profile page) lack the autocomplete attribute. Adding this attribute makes it easy for people with various disabilities to fill in the fields (correctly).
The standard common input fields (such as "name", "address", etc.) should have a
correct autocomplete attribute when using HTML5. Example: The input field "last
name" has the autocomplete attribute "family-name". See
