Most python error messages are reported to stderr rather than stdout. In
the event of a catastrophic failure executing the Pygments binary we are
likely to need to report stderr so that folks can debug the problem with
the executable.

The PHPDoc/JSDoc updates are mostly about generic "array" types that
can be made more specific.
In PHP we can remove documentation when it is 100% identical to the
type declarations in the code.
A few mistakes are fixed as well, e.g. a missing "null".
This patch also made a major mistake visible. It looks like the
$geshi2pygments compatibility map was broken since 2018. The array was
changed from values to keys via I7a852dd and some usages updated, but
one was forgotten.

Prior to the shellbox migration, if during the parsing of a page,
pygmentize failed (i.e. non-zero exit from its local shell command,
pretty much the only way a php shell exec could fail), then
SyntaxHighlight would fallback to outputting a preformatted plain
`<pre>`.
The logic still exists in the code, and is still triggered for cases
where the command reached shellbox and its result was "successfully"
communicated to MediaWiki (HTTP 200), with the boxed result reporting
the non-zero exit code on the shellbox server.
However, the more likely scenario in the new setup is that the command
times out or never reaches the server in the first place, in which
case we don't get any shell exit code. Instead, we get a Shellbox
exception since the result is unknowable.
Instead of fatalling the entire pageview with a PHP exception and
HTTP 500 from MW, use the same graceful fallback.

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.

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.

* 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.

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.
