Revert of Mac: Update sheet position when bookmark bar is shown or hidden.

Revert of Mac: Update sheet position when bookmark bar is shown or hidden. (patchset #1 id:1 of https://codereview.chromium.org/502413004/)

Reason for revert:
Broke certificate info positioning when switching tabs (http://crbug.com/419371).
I will need to come up with a better fix for this, but it looks complicated and that bug is a M39 stable blocker so reverting this first.

Original issue's description:
> Mac: Update sheet position when bookmark bar is shown or hidden.
>
> In r272421, I changed sheet repositioning on window resize to be based on
> NSWindowDidResizeNotification instead of NSViewFrameDidChangeNotification
> because it tracks window resizing much more smoothly.
>
> That caused this problem where if the browser window is vertically maximized
> (or is in fullscreen), the window size does not change when the bookmark bar
> is shown or hidden.
>
> The old code has a different bug however. If the browser window is not
> vertically maximized, showing or hiding the bookmark bar does not change the
> browser content view's frame. It moves up or down to follow the window resize
> but its frame relative to its superview remains the same.
>
> I settled for adding code to explicitly update the sheet's position when the
> bookmark bar is shown or hidden.
