SPI device migration (#490)

- Implement SPI devices in dts files for all devices
- Removed `tt::hal::spi` HAL and its configurations
- Fix for devicetree generator "boolean" support
- Remove unused custom locks in all `DisplayDevice` implementations
- Fixed some bugs with devices
- Updated XPT2046 driver
- Fix for `WifiEsp` deadlock
- Export a lot of new `math.h` symbols with `tt_init.cpp`
- Created `SpiDeviceLock` in `TactilityCore` as a wrapper for kernel SPI locking
- Improved `TactilityKernel` SPI driver.
