<pre>Send the fixed position rect to the WebProcess along with the other rects
https://bugs.webkit.org/show_bug.cgi?id=129856
Reviewed by Benjamin Poulain.
Remove the functions that pass the custom fixed position rect through
the DrawingArea, and replace them by adding this rect to the
VisibleContentRectUpdateInfo, along with the "is stable" flag. We
then set the custom fixed position rect in the web process for
stable updates.
