A zero timeout should be equivalent to using g_idle_add_full(G_PRIORITY_DEFAULT, ...)
without the nagging feeling that the wrong API was used.

[GTK] Expose title and alternative text for links in image maps
https://bugs.webkit.org/show_bug.cgi?id=84045

Reviewed by Chris Fleizach.

Source/WebCore:

Change the way we decide when the title attribute should be
used for the accessible description, by not relying in the
titleTagShouldBeUsedInDescriptionField() helper function but
in whether we have found a visible text for it or not.

This actually mimics what the Mac port does and so makes possible
to share both the layout test and its expected results.

* accessibility/atk/WebKitAccessibleUtil.cpp:
(accessibilityDescription): Update the method to determine
whether the title attribute should be used for the description.

LayoutTests:

Share test expectations among Mac, GTK and EFL ports and
remove expected failures for GTK and EFL.

* accessibility/image-map1-expected.txt: Renamed from LayoutTests/platform/mac/accessibility/image-map1-expected.txt.
* platform/gtk/accessibility/image-map1-expected.txt: Removed.
* platform/efl/TestExpectations: Removed failure expectations.
* platform/gtk/TestExpectations: Ditto.
