The shell out to get styled text is expensive.
Call Parser::incrementExpensiveFunctionCount to limit the highlighted
text snippet on a page and not reaching a timeout.
This would count each tag and not deduplicate the text snippet to count
only once or if pygmentize needs to call or is in the cache.
This also not affect Parsoid, not sure if the concept of expensive
parser function exists there

* Added Parsoid config, and refactored code slightly to
add native Parsoid handlers for parser tags exposed
by this extension.
* Enabled parsoid mode testing on the test file.
* Added html/parsoid sections on a few tests.
* Marked rest of tests as wt2html and wt2wt only since
html2wt and html2html will fail without a html/parsoid section
and there is no real benefit to adding them to all tests.
* Added a couple tests to the known failures list:
- One is because of T299103.
- The other is because Parsoid always emits attributes in the
form <tag .. foo="bar"..> instead of just <tag ... foo ..>
Since Parsoid needs to accept this format that is present on
wikis, I added a html/parsoid section for this test and
added the failures to the known failures list.

Follow up to ae07430. The method needs to be public so that
WANObjectCache can call it from a callback, but we don't expect any
external callers.

* Add rationale for each cache key's strategy being in Memc vs APCU.
* Extend pygmentize-lexers from 1 day to 1 week. It rarely changes
and already varies by version. Few things survive the day, but
there's not a reason to explicitly expire it sooner I think.
* Add a layer of Memc to the pygments-version APCU cache given that
it has a short expiry and thus relatively high miss rate.
The main rationale for this is noise in mwdebug logs since this
is currently the only thing we log by default in Logstash with prod
severity (exec INFO) during every pageview (after a php-fpm restart
which clears APCU). By adding Memc here we lose less of the cache
churn by reviving it via Memcached, and we keep the sense of there
being nothing in the logs "by default" at prod severity after restart,
e.g. don't get used to any fatigue.
Unlike the other cache keys and hooks, getVersion is the only
thing that gets called widely regardless of whether syntaxhighlight
is in use on the given page.

Extensions using Phan need to be updated simultaneously with core due
to T308443.

The order of style inclusion matters, some of our overrides were no
longer in effect.

All of the interactions with `pygmentize` have been refactored into a
new class, conviently called Pygmentize. It is responsible for getting
* pygments version (cached in APCu for 1 hour)
* generated CSS (cached in WAN by version for 1 week)
* lexer list (cached in APCu by version for 1 day)
and actually highlighting stuff! Most code paths differentiate whether
we're using a bundled version of pygments or one that has been
explicitly configured. If using the bundled one, we take shortcuts since
we already know the lexer list, have the CSS generated, etc.
ResourceLoaderPygmentsModule is added to switch between loading
generated CSS from the bundled file or Shellboxing out to get it from
pygments.
