  [WPE][Accessibility] focus change accessibility event is not exposed
https://bugs.webkit.org/show_bug.cgi?id=319475

Reviewed by Tyler Wilcock.

On WPE, if nothing else has queried the accessibility tree yet (e.g. a fresh
AT-SPI client that goes straight to listening for focus events), the very first
focus change finds no AXObjectCache and is silently dropped: onFocusChange() is
never called, and no "focused" state-changed notification is ever sent.

Add WPE alongside GTK to the platforms that lazily create the AXObjectCache on
the first focus change, matching how GTK already behaves.
