The metadata step is already conditional (checks MediaInfo JS module existence & $wgUploadWizardConfig['wikibase']['enabled'] config var), but this is not enough for launch.
We need a separate variable that prevents the metadata step from being loaded, so that we can have this additional step only on beta (and not in production) for some time.
$wgUploadWizardConfig['wikibase']['enabled'] doesn't suffice because that would also turn captions off...
Also added ['captions'] and ['depicts'], to allow each of them to be turned on/off individually, in addition to the global ['enabled']
Both default to true right now ('enabled' defaults to false), so ['depicts'] will need to be overwritten in prod config until we want to enable this, since 'enabled' is already true there.
UPDATE: changed 'depicts' to default to false, so we can let UW patch roll forward with train, without having to add config until we want to turn things on.
