Host cookie modal dialog and js modal modal dialog in NativeDialogHost

- Enable modal dialog in NativeDialogHost. This is not fully work in ChromeOS
  because e.g. user could still alt-tab away. However, setting modal would
  block user from interacting with relevant browser window and avoid crashes;
- Move dialog close code from NativeHostDialog's destructor to WindowClosing
  because a dialog's "response" signal handler could rely on the contents;
- Add "check-resize" signal handler to make GtkExpander work nicely with
  NativeDialogHost;
- Add ShowModalDialogWithMinLocalizedWidth to gtk_util for cookie and js
  modal dialog;
- Change in WidgetGtk::SetBounds to call gtk_window_move/resize always to
  keep GtkWindow's geometry info up-to-date;

BUG=none
TEST=Verify cookie prompt and js dialog on ChromeOS is hosted in a Chrome window and not occupy the whole screen.
