Mark ParserOptions suppressSectionEditLinks as safe to cache

This will split the cache for now, but pages are generally either
always rendered with suppressed edit links or always rendered without
suppressed edit links.  Previously, ParserCache would report the page
as "not safe to cache" and always bypass the cache when
suppressSectionEditLinks was set.  This isn't a problem since no one
uses this parser option yet in production, although the original
motivation was to replace the mutation of the $options array
done by the Translate extension in the ParserOutputPostCacheTransform
hook here:
