Summary: Switches the tree to use the view hierarchy for Litho nodes rather than Litho component hierarchy since Accessibility services interact with the views rendered. Includes a few more properties in the accessibility sidebar and updates to the segmented sidebar based on derived/non-derived properties for all views. Also adds functions to the AccessibilityUtil to be able to work on the accessibility sidebar while still leaving the non-accessibility sidebar unchanged. Eventually the accessibility panel will be removed from 'normal' mode and the original functions will no longer be necessary.

Summary: The second tree has access to all AX NodeInfo properties (they are not in the sidebar yet). Infrastructure set up to customize displayed information bassed on what is most useful. Descriptors for views updated to include AX functionality and non-view descriptors AX functions defaulted to null/empty. Non-view nodes (like Fragments, Window, Appication) no longer included in AX tree. Corresponding nodes will be highlighted (although not expanded) on click in either tree.
