Create a subclass for MediaSearch(Provider/Queue) and make the parent
class a more generic representation of API requests for media.

In the MediaWiki API, booleans exist or don't exist (with an empty string),
you can't check "if (bool)..." since that will always be false. The API has
a newer formatversion=2 that fixes this but we're not using that yet.
Also update the defaultSource placeholder to match the API response. If one
would only update defaultSource without the 'if'-fix, one can reproduce T66822
on a local wiki (JSON-P request instead of JSON).

Generalize MWResourceQueue and MWResourceProvider so they are
extending the general classes from ve-core. This also allows for
tests in ve-core on the resource queue system.

Change the media search widget to work with resource queues and
providers. Create providers based on the user's filerepo settings
and aggregate their responses with the media queue. Stop asking
for more results from providers that are depleted.
Also fixes a rather nasty infinite-loop bug where the API returns
only very few images, and the UI keeps asking for more.
