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.

Use it instead of Content::getDeletionUpdates and Content::getSecondaryDataUpdates.

Ref discussion on T42284.
Test plan:
* Create gadget A with a .css file only. (Maybe mark as 'hidden')
* Create gadget B with .js file, and peers=A.
* Verify that enabling B will result in B being loaded as general module,
and A being loaded as page style module.

T87871 formally introduced the concept of a styles module,
which sets mw.loader.state to "ready" when loaded through addModuleStyles().
Previously, addModuleStyles couldn't safely do that because a module may
contain scripts also, in which case mw.loader must still load the (rest)
of the module (causes styles to load twice).
In MediaWiki core or extensions this is easily avoided by calling not
calling both addModules() and addModuleStyles().
For Gadgets we call both as a workaround to allow users to provide styles
(without a FOUC), but also to provide scripts+styles. Since we don't declare
which one is intended (and some gadgets do both), we loaded them both ways.
This will no longer be allowed in the future (see T92459).
The new 'type=styles' Gadget attribute promises to ResourceLoader that a
gadget only contains styles.
Impact:
* [Bug fix] When mw.loader requires a styles module that already loaded,
it will not load again.
* [Feature] It is possible for a general scripts+styles gadget to depend on
a styles gadget. Previously this caused the styles to load twice.
* Specifying type=styles will load the module through addModuleStyles() only.
Use this for modules that contain styles that relate to elements already
on the page (e.g. when customising the skin, layout, or article content).
* Specifying type=general will load the module through addModules() only.
Use this if your module contains both scripts and styles and the styles
only relate to elements created by the script. This means the styles do not
need to be loaded separately through addModuleStyles() and will not apply
to noscript mode.
Effective difference:
* Gadgets with only styles: We assume type=styles.
This fixes the main bug (styles loading twice) and requires no migration!
* Gadgets with only scripts: We assume type=general.
This requires no migration! (And: No more empty stylesheet request)
* Gadgets with scripts (with or without styles): We assume type=general, but
unless type=general was explicitly set we'll still load it both ways so
that the styles apply directly on page load.
If this is not needed, set type=general.
If this is needed, it should become two separate modules. We do not support
a single module having two purposes (1: apply styles to the page,
2: provide scripts+styles). The styles module should be separate.
It can be made hidden, and listed as dependency of the other module.
The latter case is detected on page load and results in a console warning
with a link to T42284.

For consistency with rest of MediaWiki, especially CodeEditor.
Note that this will cause dirty diffs for any definition pages created
before this patch, but that's not a big deal.
Change-Id: I3ed4b4aa7d18c489b9a322f67ea6ea31e610a257
Implements:
* Gadget definition content and content handler
* Basic validation for gadget definition content
* GadgetDefinitionNamespace implementation of GadgetRepo
* DataUpdates upon editing/deletion of Gadget definition pages
* EditFilterMerged hook for improved error messages
* 'GadgetsRepoClass' option to switch GadgetRepo implementation used
* Lazy-load the GadgetResourceLoaderModule class so we don't need to
load each individual gadget object unless its needed
Note that Special:Gadgets's export feature intentionally doesn't work
yet, and will be fixed in a follow up patch.
