Aaron Schulz 3c7f29a6b9 Add small HtmlCacheUpdater service class to normalize purging code (2)
This is a re-submit of 35da1bbd7c, which was accidentally merged before
CR (and reverted with aa4da3c2e8).

The purge() method handles purging of both file cache and CDN, using
a PRESEND deferred update. This avoids code duplication and missing
file cache purge calls.

Also:
* Migrate HTMLCacheUpdate callers to just directly using HTMLCacheUpdateJob
* Add HtmlFileCacheUpdate class and defer such updates just like with CDN
* Simplify HTMLCacheUpdate constructor parameters
* Remove BacklinkCache::clear() calls which do nothing since the backlink
  query does not actually happen until the job runs
