[UI5 Support]: Model `loadData`, `setData`, and `setJson` UI5 methods

[data-douser]

High-level Tasks

Ensure missing UI5 modeling is addressed in our CodeQL query libraries, unit tests, and (if possible) queries that detect potential insecure use of UI5. This issue focuses on addressing potential gaps such as:

• both JSONModel and XMLModel have a loadData method that gets data via ajax request.
• the setData and setJson methods it can be filled with arbitrary tainted data.
