Fix missing frame or wrong frame position when resize starts

When multi-thread renderer is used, delay the report to draw to the
first doFrame in ResizeFrameThread. Otherwise we could unfreeze the
window before the frame is drawn.

Also when content draw bounds is updated for the first frame, let
content draw before ResizeFrameThread so that the bounds get applied.
