When gfx::Animation::ShouldRenderRichAnimation() returns false,
we shouldn't do heavy animation. In favor of this, disable
the following animations:

* find bar
* info bar
* download shelf
* bookmarks bar

While doing this, fix a bug in gfx::SlideAnimtion::Hide().
As the previous comment mentioned, we should pass 1.0
to AnimateToState() in order to skip to the end of animation.
The parameter represents the progress of each animation, not
the value.
