Simey Lameze f1be9b6544 MDL-75910 core_form: Allow editor field to set a hidden label
When an editor is used in a form as part of a group, it is missing its
label element.

This happens because there is no inline template for the editor, and
therefore it reverts to using the old `toHtml` function. The legacy
function does not cater to the editor being in a group, and therefore
does not add the hidden label.

In addition, the hiddenLabel attribute was missing from the editor
element. This is a semi-standard element but must be added to each
supporting element.

Both the missing inline template for the editor, and the hidden label
attribute must be present:
- If the hidden label attribute is not present, then the standard inline
  template will add a visible label within the group.
- If the inline editor template is missing, then the label is not shown
  at all.
