API warnings and error messages are currently hard-coded English
strings. This patch changes that.
With a few exceptions, this patch should be compatible with non-updated
extensions:
* The change to ApiBase::$messageMap will blow up anything trying to
mess with it.
* The changes to the 'ApiCheckCanExecute' hook will cause a wrong
(probably unparsed) error message to be emitted for extensions not
already using an ApiMessage. Unless they're currently broken like
Wikibase.

Database queries used to get user's watchlist items in API are quite
complex due to number of options oferred by the API.
Generating the query is moved to WatchedItemQueryService.
ApiQueryWatchlistRaw no longer contains database-related code.
Simple user watchlist item lookups should use WatchedItemStore.
ApiQueryWatchlistRaw tests have been introduced in
