Fix bug #10624988 Incorrect mirroring of RAM and Internal Storage for Apps screens in Settings

- well this CL is only for preventing a wrong rendering (the real CL would need to be one latter
and would need to fix the onDraw(Canvas) for LinearColorBar so that it takes care of the layout direction)
- force LTR layout direction on the LinearColorBar, hence preventing the two TextView to render their
text "in the middle".
- use BidiFormatter to wrap number strings
