[GTK] Don't log document events in DRT
https://bugs.webkit.org/show_bug.cgi?id=73746

Reviewed by Martin Robinson.

New unit test to check events when reloading a document. This
replaces the former document-reload-events.html layout test.

* tests/testatk.c:
(updateLoadingEventsResult): New, updates a global variable to
allow checking later on that the right signals were emmitted.
(documentLoadingEventCallback): New, global listener for load-complete
and reload signals over the document object (the web area).
(testWebkitAtkDocumentLoadingEvents): New unit test, globally
connects to document-related signals and check they are properly
emitted when reloading the web view.
(main): Added new test.
