sw content controls, dropdown: add LOK API

- expose the available list items in a new "items" key of the
LOK_CALLBACK_CONTENT_CONTROL callback

- add a new lok::Document::sendContentControlEvent() function to be able
to select a list item from the current drop-down

- add a new listbox to the gtktiledviewer toolbar to select a content
control list item when the cursor is inside a dropdown

- add tests for the array API of tools::JsonWriter
