Siddharth VP 1f7b9d90df Support JSON files in gadgets
The parsed content of JSON files in the gadget is made available from the
gadget's JS files via require(). That is, MediaWiki:Gadget-data.json (or
Gadget:data.json) is available as `require('./data.json')`. This is
supported for both MediaWikiGadgetsDefinitionRepo and
GadgetDefinitionNamespaceRepo. The JSON parsing is done server-side.

JSON can only be used in "package" gadgets - in which the JS files can
also be invoked via require().

Also added a test for GadgetResourceLoaderModule.
