Summary:
Fixed issue with DebugComponentDescriptors being left out of accessibility tree so the AX tree now includes all Litho view nodes (not Litho accessibility nodes yet). Litho drawables have no accessibility properties so these are not included. Also changed default for getAXChildAt to do whatever the original view tree does for that node and added a getAXChildCount function to better customize the accessibility tree.
Segmented the ax sidebar into properties directly form the view and properties derived from the AccessibilityNodeInfo.
