Fix bug #7536213 UI should be mirrored for RTL languages (people, dialer, in-call)

- add start/end properties aside to left/right ones
- update Gravity to START/END
- add mirrored version of Drawables
- use android:textAlignment="viewStart" when needed on TextView
- use android:textDirection="ltr" for when needed for Phone Numbers
