Let Drupal determine enctype of a form

Problem/Motivation

We want to block POST requests to our site when the encoding is set to multipart/form-data however the Webform module sets the encoding for all forms it controls to this value. Now that Drupal can dynamically add the multipart/form-data encoding to forms that require it there is no reason for Webforms to hardcode this value.

Proposed resolution

Remove the hardcoded encoding type from Webform module.

$form['#attributes']['enctype'] = 'multipart/form-data';
