[GTK][a11y] Add a build option to enable ATSPI

• Component: WebKitGTK
• Status: RESOLVED FIXED

[Carlos Garcia Campos]

Add USE_ATSPI build option that disables ATK and enables the new atspi based implementation, for now just adding stubs and build fixes with isolated tree enabled.

Instead of adding more #if throughout the platform-independent source, it would be cleaner to move this mac implementation to AXObjectCacheMac.mm, and add a new implementation for atspi.

Same comment for AXObjectCache::isIsolatedTreeEnabled, initializeSecondaryAXThread and usedOnAXThread.

This doesn't seem related to enabling isolated tree, so perhaps you can submit this change as a separate patch.

Could we move these platform-specific properties to initializePlatformProperties? That way we wouldn't have to #if throughout here.

Right, this is weird here, The reason of this change is because WTR uses the WebCore wrappers, and including TextIterator.h from the header pulled too many things that caused linking errors. I'll split the patch.
