Scroll the config panels with ClassicAPI's scroll bar

Browse Source 
pfUIScrollFrameTemplate (api/ui-widgets.xml) is a ScrollFrame with
pfUIScrollBarTemplate inside its right edge and a Content scroll child,
driven by ScrollUtil.InitScrollFrameWithScrollBar. The panels keep a
ScrollFrame because the engine measures its range from the shown frames
inside the content, which the hand-placed config rows rely on. The bar
follows OnScrollRangeChanged instead of an OnUpdate poll per panel.

A panel measures its range once its rows are built, and the search
results measure theirs with UpdateScrollChildRect instead of hiding,
re-attaching and scrolling a frame later. Clearing the search measures
again too.

CreateScrollFrame and CreateScrollChild have no users left, and nothing
called CreateTabFrame or CreateTabChild; all four are gone. pfQuest's
compat layer brings its own copies of the scroll helpers.

A ScrollFrame for free-form content, with pfUIScrollBarTemplate inside its
right edge. Put the content in frame.Content, which spans the frame: the
engine measures the scroll range from the shown frames inside it, so the
content needs no height. Changes inside it are not measured until
frame:UpdateScrollChildRect().
