Data Type icons of Manage Custom Data Types dialog - visual design

DMN Data Types dialog uses the following PF pattern: https://www.patternfly.org/pattern-library/content-views/tree-list-view/. As such it includes a list. We need list icons for two types of list items:

• Simple custom Data Types (basically means not nested date types)
• Structured custom Data Types (basically means nested data types)
