Refactored CYD-2432S028R board initialization, touch, and SD drivers (#314)
* feat(board): add support for CYD-2432S028R board and update XPT2046 driver

- 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.

* Added a new GitHub Actions job to build firmware for the cyd-2432s028r board
using the existing build-firmware action. This ensures continuous integration
coverage for the new board alongside other supported ESP32 variants.

* Removed unnecessary file

* Refactor CYD-2432S028R board initialization, touch, and SD drivers

- Updated board CMakeLists to use `XPT2046-Bitbang` instead of `XPT2046`.
- Added `YellowSdCard` support and initialized SD card in board configuration.
- Updated SPI pin assignments for touch and SD card to match hardware setup.
- Refactored touch driver to use bit-banged SPI with proper start/stop handling.
  - Touch adaptation was based on a merge of:
    - https://github.com/NellowTCS/Tactility/blob/main/Drivers/XPT2046-Bitbang/Source/XPT2046-Bitbang.cpp
    - https://github.com/ddxfish/XPT2046_Bitbang_Arduino_Library/blob/main/XPT2046_Bitbang.cpp
  - Calibration is currently static in code:
        Calibration cal = {
            .xMin = 100,
            .xMax = 1900,
            .yMin = 100,
            .yMax = 1900
        };
    This removes the need for manual touchscreen calibration, but code was adjusted to support dynamic calibration in the future.
- Added comments and constants for software SPI touch pins.
- Updated `YellowDisplay` to use new touch driver configuration.

* Refactor XPT2046 touch driver: replace Bitbang with SoftSPI implementation, update CMake and README files
