Feature: #70332 - EXT:form - Add HTML4 / HTML5 attributes to the wizard

See Issue #70332

Description

The form wizard should support a wide set of attributes. At the moment the wizard is able to set some attributes, but this attribute-set is not complete and does not include HTML5 attributes.

The patch extends the wizard to set all universal HTML and HTML5 attributes based on selfhtml documentation version 8.1.2.

Currently supported attributes

accept, acceptcharset, accesskey, action, alt, checked, class, cols, dir, disabled, enctype, id, label, lang, maxlength, method, multiple, name, placeholder, readonly, rows, selected, size, src, style, tabindex, title, type, value

New attributes

autocomplete, autofocus, contenteditable, contextmenu, draggable, dropzone, height, hidden, inputmode, list, max, min, minlength, novalidate, pattern, required, selectionDirection, selectionEnd, selectionStart, spellcheck, step, translate, width, wrap

The type attribute will be extended with the following HTML5 types:

color, date, datetime, datetime-local, email, month, number, range, search, tel, time, url, week

Each element is now able to set the HTML universal attributes and element specific attributes.

Universal attributes are:

accesskey, class, contenteditable, contextmenu, dir, draggable, dropzone, hidden, id, lang, spellcheck, style, tabindex, title, translate
