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.
Bug: T106177

Register the "Gadget", "Gadget definition", and their respective talk
namespaces. It will not be possible to create any pages in the Gadget
and Gadget definition namespaces due to the "gadgets-edit" and "gadgets-
definition-edit" rights not being granted to any groups.
Depends on Iaf8b44d02adf9 in MediaWiki core.

The time has come to stop supporting legacy gadgets that haven't
migrated to ResourceLoader yet.
For many Gadgets, migrating to ResourceLoader will be as easy
as adding "[ResourceLoader]" to its definition on MediaWiki:Gadgets-definition.
However for older gadgets, they may need more maintenance. Though
similarly they may've already been malfunctioning silently.
The most common techniques used by legacy scripts, and what their
equivalents are in modern JavaScript, see:

MediaWiki core change I04b1a384 added support for i18n of API module
help. This takes advantage of that while still maintaining backwards
compatibility with earlier versions of MediaWiki.
Once support for MediaWiki before 1.25 is dropped, the methods marked
deprecated in this patch may be removed.
