JS - Handle correctly hierarchy of fields (#13133)

Browse source 
* JS - Handle correctly hierarchy of fields
  - it aims to fix #13132;
  - annotations can inherit their actions from the parent field;
  - there are some fields which act as a container for other fields:
    - they can be access through js so need to add them with an empty type (nothing in the spec about that but checked in Acrobat);
    - calculation order list (CO) can reference them so need make them through this.getField;
    - getArray method must return kids.
  - field values are number, string, ... depending of their type but nothing in the spec on how to know what's the type:
    - according to the comment for Canonical Format: https://www.adobe.com/content/dam/acom/en/devnet/pdf/pdfs/PDF32000_2008.pdf#page=461
    - it seems that this "type" can be guessed from js action Format (when setting a type in Acrobat DC, the only affected thing is this action).
  - util.scand with an empty string returns the current date.
