LOOKDEVX-1091 - Add Ufe log on console to notify shader attribute without a default value

[selvatm-autodesk]

• The goal is to notify the user when a property of any shader lacks a default value.
• The properties that lack a default value will start to log a warning when the user interacts with them in the editor (that involves the get() of the property value).
• Known attributes are maintained in a list (std::unordered_set) to avoid being too verbose for properties we have already printed on Console.
