Expose ListView.listItemPrefabs for read-only access

[ryan-at-melcher]

ListView (and by extension, GridView) have a prefab list field that is marked internal. This field, if exposed, would provide users the ability to query information about the source prefabs that make up the list.

My use case is a GridView with a dynamic cross axis item count. To know how many columns fit, I use the width of a prefab versus the width of the grid. It feels appropriate to obtain this information directly from the prefab. Currently, I can accomplish my goal by calling GetChild() on the view and referencing the size of the instantiated prefab (although I must check to ensure the list has children).

Is there anything I'm missing about exposing the prefab list for read only access?
