qdoc: Remove all collision node stuff from qdoc

Now that the qdoc link command has ability to tell qdoc which module
contains a link target or whether to link to a QML or CPP entity,
collision pages should no longer be necessary. In fact, qdoc hasn't
been generating any collisions for some time. This task removes all
the collision node code from qdoc.

Task-number: QTBUG-40506
