Fix bug #6427629 Clean up layout direction APIs

- canResolveXxx() should be hidden
- resetResolvedXxx() should be hidden
- resolveDrawables(), resolveLayoutDirection(), resolvePadding(), resolveTextAlignment(), resolveTextDirection() should be hidden
- onResolvedXxx() should be merged into one callback
- fix also an issue with setting the layout direction of the drawable in ImageView
- fix also an issue with checking if TextAlignment can be resolved
