feat: implement SPIBusFast driver with 90° rotation for AXS15231B QSPI
 - Add SPIBusFast bus driver with partial updates support - Enable LVGL partial mode instead of full frame updates - Implement 90° rotation with pixel coordinate transformation - Add RTOS task for double buffering - Support QSPI 4-wire interface for AXS15231B controller
