* Pass rootNode to the constructor
* Rename getters to match CommentItem/HeadingItem/ThreadItem
value classes.
* Always build the thread tree so CommentItem's always have
and ID and replies/parent.

Rather than the <body> node, we were passing <body>'s first child.
Current implementation of CommentParser::getComments() doesn't fail
the tests in spite of this because the XPath query incorrectly returns
results relative to the document's real root node, but these tests
would start failing after I2441f33e6e7bad753ac830d277e6a2e81ee8c93d.
Follow-up to 3e6ab2c4d2.

The expected HTML was wrong, a '<br />' tag inside 'data-mw' was
somehow turned into '<br ></span>'. No idea how that happened.
Something must be wrong with the HTML parsing in JS tests, which
were used to generate this file.

This method shouldn't be required on the server. Leave comments
relating to it in addListItem so JS & PHP can be kept in sync.

In JS, strings are internally encoded as UTF-16, and properties like
.length return values in UTF-16 code units.
In PHP, strings are internally encoded as UTF-8, and we have the
option of using methods that return bytes like strlen() or UTF-8 code
units like mb_strlen().
However, the values produced by preg_match( …, PREG_OFFSET_CAPTURE )
are in bytes, and there's nothing we can do about that. So let's use
bytes throughout, mixing the two types results in meaningless numbers.
Then in the test code, we have to calculate UTF-16 code units offsets
based on the UTF-8 byte offsets.
We also have to copy the entire workaround for mw:Entity nodes… Maybe
the parser should be fixed to return the real nodes for ranges' ends
in this case.

In JS tests, we load the documents via mw.template, which apparently
causes the <html>, <head> and <body> tags to disappear, resulting
in the ranges not matching in PHP tests (and the real document).
Put in a big hack that makes them match, and update the JSON files.

Profiling reveals that >87% of the run time of our test suite is spent
in this tiny method. Apparently, DOMNodeList::item() is extremely slow
(possibly it's linear time instead of constant time?).
Profiled using XDebug and KCacheGrind:
https://phabricator.wikimedia.org/F31815264
We can calculate the child's index in its parent by counting its
precending siblings instead, which turns out to be much faster.
Before:
1. 275444ms to run DiscussionToolsCommentParserTest:testGetComments with data set #2
2. 12668ms to run DiscussionToolsCommentParserTest:testGetComments with data set #3
...
After:
1. 9545ms to run DiscussionToolsCommentParserTest:testGetComments with data set #2
2. 5549ms to run DiscussionToolsCommentParserTest:testGetComments with data set #3
...
That's still kind of slow but now it's bearable to run the test suite.

* Not to be confused with the Parsing Team's
"Great Parser JS to PHP port of 2019"
Gasp as OR hacks are changed to null coalescing operators.
Applaud as variable declarations are dropped.
Cheer as parameters and return values are type-hinted.
Shudder as DomNodeLists have no indexOf method.
Moving discussion parsing to the server should allow
us to implement much cleaner APIs for commenting.
