Add the centralnoticebannerchoicedata API module

Creates a Web API access point for banner choice data, for use when
direct inter-wiki DB queries are not possible.

This is part of a series of changes to shift banner selection partly
to the client. This change itself does not modify CN functionality
when serving banners.
