[GTK] Expose menu items and menus as children of a menu bar

• Component: Accessibility
• Status: RESOLVED FIXED

[Mario Sanchez Prada]

In the following example:
http://test.cita.illinois.edu/aria/menubar/menubar1.php

Theres some WAI-ARIA compliant HTML exposing a menu bar with 4 menu items, where each of them pop out a menu when activated, showing some more menu items in those menus. That is, the typical menubar -> menuitems -> menu (for each menu item) -> menu item (for each menu) layout :-)

Problem is that WebKitGTK should be exposing something like this (as for roles):

  Menubar
   |---> menu item
   |      `---> menu
   |             |---> menu item
   |             |---> menu item
   |             `---> menu item
   |---> menu item
   |      `---> menu
   |             |---> menu item
   |             |---> menu item
   |             `---> menu item
   |---> menu item
   |      `---> menu
   |             |---> menu item
   |             |---> menu item
   |             `---> menu item
   `---> menu item
          `---> menu
                 |---> menu item
                 |---> menu item
                 `---> menu item

However, what is currently exposing is the following:
  Menubar
   |---> panel
   |---> panel
   |---> panel
   `---> panel

...which is obviously wrong, preventing ATs from checking the contents of those menus

Patch proposal + Layout test

Attaching simple patch to fix this along with a cross platform test (needs adding new results for other platforms, say, Mac and Win)

It looks like we're calling parentObjectUnignored()->ariaRoleAttribute() potentially three times. I think that value should be stored local. parentObjectUnignored() can be little expensive.

I'll fix that right before committing.

Thanks!
