Use the '--json' flag to get Pygments to output its list of supported
lexers in a machine-readable format. Support for this flag was added (at
our request) to Pygments and included in the 2.11 release[1].
Tested by running updateLexerList.php and confirming empty diff.

When using a non-bundled Pygments (which is required on Windows, as the
bundled version is an ELF binary), we call into the Pygments executable
to generate the list of supported languages (lexers). This list seems to
occasionally include carraige returns, causing some languages to not be
processed correctly. Trim those CRs out so the language list is
accurate.

Replacing the HIGHLIGHT_MAX_LINES and HIGHLIGHT_MAX_BYTES constants with $wgSyntaxHighlightMaxLines and $wgSyntaxHighlightMaxBytes respectively, so sysadmins can adjust the limits to their needs if performance is not of their concern.

Python on Windows requires the SystemRoot environment variable in order
to initialize its internal RNG, so make sure that is passed along to the
subprocess.

Steps to reproduce:
* Make a wikitext page with <syntaxhighlight line="sure">…</…>.
* Edit with VisualEditor and make an unrelated change to the content.
* Save.
* Before the attribute was always replaced with line="1".
* With this patch the old value stays untouched.

Skip the expensive check,
for example when no highlighting is wanted because there is no lexer
Also all validation of the tag is now processed and
invalid tags also not counted.

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
