Cleanup: Improve API and documentation of interface_view.cc 

File documentation was outdated and could use general improvement.
Function names didn't really reflect the level they are operating on.

/** \file
* \ingroup edinterface
*
* This part of the UI-View API is mostly needed to support persistent state of items within the
* view. Views are stored in #uiBlock's, and kept alive with it until after the next redraw. So we
* can compare the old view items with the new view items and keep state persistent for matching
* ones.
* Code to manage views as part of the regular screen hierarchy. E.g. managing ownership of views
* inside blocks (#uiBlock.views), looking up items in the region, passing WM notifiers to views,
* etc.
*
* Blocks and their contained views are reconstructed on every redraw. This file also contains
* functions related to this recreation of views inside blocks. For example to query state
* information before the view is done reconstructing (#AbstractView.is_reconstructed() returns
* false), it may be enough to query the previous version of the block/view/view-item. Since such
* queries rely on the details of the UI reconstruction process, they should remain internal to
* `interface/` code.
