This commit introduces Arabic text shaping in the chat application by adding `ArabicShaping.cpp` and `ArabicShaping.h` for handling contextual forms and visual reordering. The rendering logic in `ChatScreen.cpp` is updated to utilize this new functionality, adjusting cursor positions accordingly. Other UI components, including `UIControl_Base.cpp`, `UIControl_Label.cpp`, and `UIControl_SaveList.cpp`, are modified to ensure proper display of Arabic text. Additionally, `Font.cpp` is enhanced with methods for efficient rendering of pre-shaped text.
