Collect extra logging if ReactViewGroup.dispatchDraw crashes

Summary:
dispatchDraw,  dispatchGetDisplayList, updateDisplayListIfDirty, recreateChildDisplayList, etc, can all crash internally for a variety of reasons and it can be very tricky to track down the root cause. This isn't a fix, this just adds extra logging to hopefully make debugging easier.
