Cleanup CFWL_Widget code to return CFX_RectFs where appropriate

This Cl changes the various Get*Rect methods in CFWL_Widget to return CFX_RectF
classes instead of taking an out parameter. The Repaint method is split into
Repaint() and RepaintRect() in order to change the param to a const CFX_RectF&
from a CFX_RectF*.
