Revert of MacViews: Implement Set/Get*Bounds for NativeWidgetMac

Revert of MacViews: Implement Set/Get*Bounds for NativeWidgetMac (https://codereview.chromium.org/353643002/)

Reason for revert:
Breaks on 64-bit mac (doh). NSRect is declared differently, so a forward declare won't work.

Original issue's description:
> MacViews: Implement Set/Get*Bounds for NativeWidgetMac.
> 
> In toolkit-views, "Bounds" corresponds to the NSWindow frame (including
> titlebar and borders). This CL maps that onto NSWindow in
> InitNativeWidget, GetWindowBoundsInScreen, GetClientAreaBoundsInScreen,
> SetBounds and SetSize, performing the required coordinate system
> conversions.
> 
> 5 more views_unittests pass after this:
> BubbleDelegateTest.NonClientHitTest
> CustomFrameViewTest.{CannotMaximizeHidesButton, DefaultButtonLayout,
> LeadingButtonLayout}, ViewTest.ConversionsToFromScreen.
> 
> The CL also adds a cross-platform WidgetTest.GetWindowBoundsInScreen to
> ensure the behavior is consistent across platforms, and because there
> wasn't really anything to cover just bounds setting (e.g. to verify the
> coordinate flipping Cocoa needs to do).
> 
> BUG=378134
> TEST=views_unittests
