[MacViews] Implement size constraints for app windows.

This works the same way as NativeAppWindowCocoa by setting
properties on the NSWindow in OnSizeConstraintsChanged.

This also moves some code in common with NativeAppWindowCocoa
out to c/b/ui/cocoa/apps/nswindow_util.h. More code will be moved
there as they're implemented on MacViews, e.g.
CalculateDraggableRegions.
