/**
 * Returns HTML for a form element.
 *
 * Each form element is wrapped in a DIV container having the following CSS
 * classes:
 * - form-item: Generic for all form elements.
 * - form-type-#type: The internal element #type.
 * - form-item-#name: The internal form element #name (usually derived from the
 *   $form structure and set via form_builder()).
 * - form-disabled: Only set if the form element is #disabled.
 *
 * In addition to the element itself, the DIV contains a label for the element
 * based on the optional #title_display property, and an optional #description.
 *
 * The optional #title_display property can have these values:
 * - before: The label is output before the element. This is the default.
 *   The label includes the #title and the required marker, if #required.
 * - after: The label is output after the element. For example, this is used
 *   for radio and checkbox #type elements as set in system_element_info().
 *   If the #title is empty but the field is #required, the label will
 *   contain only the required marker.
 * - invisible: Labels are critical for screen readers to enable them to
 *   properly navigate through forms but can be visually distracting. This
 *   property hides the label for everyone except screen readers.
 * - attribute: Set the title attribute on the element to create a tooltip
 *   but output no label element. This is supported only for checkboxes
 *   and radios in form_pre_render_conditional_form_element(). It is used
 *   where a visual label is not needed, such as a table of checkboxes where
 *   the row and column provide the context. The tooltip will include the
 *   title and required marker.
 *
 * If the #title property is not set, then the label and any required marker
 * will not be output, regardless of the #title_display or #required values.
 * This can be useful in cases such as the password_confirm element, which
 * creates children elements that have their own labels and required markers,
 * but the parent element should have neither. Use this carefully because a
 * field without an associated label can cause accessibility challenges.
 *
 * @param array $variables
 *   An associative array containing:
 *   - element: An associative array containing the properties of the element.
 *     Properties used: #title, #title_display, #description, #id, #required,
 *     #children, #type, #name.
 *
 * @return string
 *   The constructed HTML.
