We never paint scroll corners. The only thing we need them
for is so that the vertical and horizontal scrollbars don't
overlap each other. So, that's the only place left that
still computes a scroll corner rect.
We don't support resizers. Remove the code for them as well
as the CSS resize property.

No change in behavior. Just deleting dead code.
Also removes ScrollAnimatorNone since it's unused.
We'll need to bring some of this back, but we'll
do that when we get rid of composited scrolling.

FrameView doesn't really need to know about the child widgets,
which are just Scrollbars now.
I also deleted some dead code from Widget and removed FrameWidget
since we don't need that abstraction now.

We only allow overflow scrolling. The frame isn't special.
This is a first step in making that happen. There's a lot of
code to remove after this patch, but this gets rid of
ScrollView and a bunch of frame-level scrolling code.
Had to add in a FrameWidget class so that Scrollbar.cpp had
a way of getting to FrameView::removeChild without pulling
a core class into platform. This might go away when we rip
out the Widget tree if we made it so that FrameView didn't
keep a list of Scrollbar instances.
Modified scrollbar.html to use overflow scrolling instead of
frame level scrolling. Once we get rid of the split between
Document and documentElement, we'll be able to make the root
element in the page scrollable as well (i.e. any child of the
Document).
