Factor find in page out of WebContents and into the view, since it is almost

all view specific. Rename find in page controller to be "FindBarWin", and
find in page view to be "findBarView" (since this is not Windows specific, but
"Views" specific).

I did lots of simplification and moving around of the find in page API. I
coalesced several of the show functions into one master function on the view.

I removed some other sizing and window updating code from WebContents and moved
it to the view.
