AX: Refactoring of TextMarkers and TextMarkerRanges support on Mac.
https://bugs.webkit.org/show_bug.cgi?id=230558
rdar://83625620
Reviewed by Chris Fleizach.
This is the first change in a series aimed at supporting TextMarkers off of the
main thread.
This patch adds the AXTextMarker and AXTextMarkerRange classes to provide the
functionality that is currently implemented through VisiblePositions,
CharacterOffsets and AXTextMarkerRefs.
AXTextMarker encapsulates the AXIDs of the backing AXObjectCache and
AXIsolatedTree, as well as the AXID of the corresponding AXCoreObject. This
allows for the retrieval of the TextMarker properties without having to
resource to the underlying DOM and RenderTree objects.
The following Mac AX API attributes are now implemented without hitting the
main thread using AXTextMarker and AXTextMarkerRange:
AXUIElementForTextMarker
AXTextMarkerRangeForTextMarkers
AXStartTextMarkerForTextMarkerRange
AXEndTextMarkerForTextMarkerRange
This patch also includes an update of several layout tests related to
TextMarkers.
