Create DTS files for all devices and implement I2C changes (#466)
Devictree changes: - Create DTS files for all remaining devices - Update corresponding `devicetree.yaml` - Remove `i2c` configuration from corresponding `tt::hal::Configuration` Apps & HAL: - Removed I2C Settings (we'll make a new one later after I rework that part of the HAL) - Delete TactilityC GPIO and I2C functionality - Delete Related SystemEvent types - Refactor `tt::hal::i2c` to only use `struct Device*` wrapping Scripting: - Fix DevicetreeCompiler boolean parsing - Create `build-all.py`
