Customise simple search widget instance

Description: Customise simple search widget instance (columns to display, filter options and sort)

Breakdown: 

• Build a widget query based on app definition
• Sort results within widget
• Save custom app widgets

Development Tasks: 

1. Explore final-form vs react-hook-form or similar
2. Create paginated form which takes in a definition, then returns the correct form component for that type
3. Build a widget form based on widget definition and type (For now just SimpleSearch, this will have to be custom made for each WidgetType)
4. Dynamic form creation
   1. Filter columns
   2. Result columns
   3. Sorting
   4. Extra fields
5. Ability to POST this widget properly -> potentially needing submit manipulation

Display of configured widget is handled by work already done in https://issues.folio.org/browse/ERM-1561
