Reasons:
* Various other methods dealing with ranges already live there
* It would be neat if ContentThreadItem was just a value class
without a lot of logic, similar to DatabaseThreadItem,
particularly for writing unit tests
* The methods access global state through Title, which can't
be fixed while they're in ContentThreadItem (see I9dfccc83)
The computation is now always done, instead of only when needed,
but that's a small drawback, since it's fast (fast enough that
I don't see the difference in the time taken when running tests),
and we were already computing it for all comments in many places.

This might be a matter of personal preference. Not sure if it's
worth it. Both is well readable. On the other hand, the method
exists. Why not use it?

MediaWiki's PHPCS plugin requires documentation comments on all
properties, unless those properties are typed.
This has potential to introduce bugs – in particular, because typed
properties without a default value will throw an exception if their
value is accessed before it's defined, while previously they defaulted
to null. I fixed this when I found it (making them nullable and null
by default), but I may have missed some cases.

Rename ThreadItem to ContentThreadItem, then create a new ThreadItem
interface containing only the methods that we'll be able to implement
using only the persistently stored data (no parsing), then create a
DatabaseThreadItem. Do the same for CommentItem and HeadingItem.
ThreadItemSet gets a similar treatment, but it's basically only for
Phan's type checking. (This is sad.)
