[Resources] Add missing or implied dependencies
* mediawiki.action.watch.ajax:
-- Depends on mediawiki.api.watch>mediawiki.api>mediawiki.util
-- But also uses mw.util itself, so adding it here as well. mw.Api might one day not use mw.util
* mediawiki.special.block: Uses mw.util.isIPv4Address / mw.util.isIPv6Address
* mediawiki.special.changeemail: Uses mw.util.validateEmail
* mediawiki.legacy.upload: Uses mw.util.wikiScript
* Uses mw.util.wikiUrlencode
