Subject: [PATCH] Make Special:Whatlinkshere.php transcludable

This commit makes Special:Whatlinkshere transcludable by extending
SpecialWhatLinksHere with IncludableSpecialPage. It also adds a condition
in the showIndirectLinks function to avoid displaying the form when the
page is being transcluded.

Bug: 35486
