Document the ClientRect* vs DOMRect* situation

Add a UseCounter for the ClientRectList.item() method. Adding
[MeasureAs=ClientRectListItem] to the existing single line actually
only counts the named getter, but split them in the IDL for clarity.

Remove the ClientRectList FIXMEs that have been there since the
interface was added in 2009: https://trac.webkit.org/changeset/40837

DOMRectList or an array of ClientRect/DOMRect would not throw here, so
there's no reason to ever implement the requirements of the old spec.
