Implemented CYD-2432S028R board and update XPT2046 driver (#308)

- Added CONFIG_TT_BOARD_CYD_2432S028R in Kconfig.
- Included support for CYD2432S028R in Boards.h and board.cmake.
- Updated Xpt2046Touch driver to use configuration->spiDevice instead of SPI2_HOST when creating the SPI handle.
- Note: SD card is not working on this board yet.

This commit introduces full support for the CYD-2432S028R board and improves the touchscreen driver flexibility by allowing dynamic SPI device configuration. SD card functionality still needs to be implemented.
