?withgadget query parameters allows for ad-hoc loading of gadgets
(after passing all other basic checks). This was recently added in
I5b30d4e.
In T29766#7611796 Gergo raised concerns about how this can be
potentially abused.
This patch aims to restrict the feature by giving gadgets latitude
to either use it or not depending on the nature of the gadget.
The patch does so by adding `supportsUrlLoad` option that gadgets
(maybe those deemed safe) can use it to opt-in to the parameter.
By default gadgets don't support it, so it can be enabled for each
on a case-by-case basis.

Allow specifying page actions ('view', 'edit', 'history', etc) in
gadget definitions. If specified, the gadget is run only on the given
page action(s).
This is especially useful for default gadgets like RefToolbar[1] and
TextReactions[2] that only need to be loaded while editing.

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.

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.
