Tab5 audio, I2C improvements, UiDensity moved to lvgl-module and cleanup (#506)

- UiDensity moved to lvgl-module
- Deleted tt_hal and tt_hal_gpio (breaks apps, but will fix those right after merging)
- Added I2C 8 bit register operations
- Added device.properties to simulator
- Improved Tab5 hardware init, implement audio
- Add README.md to kernel

+# TactilityKernel
+
+TactilityKernel is the core component of the Tactility project, providing a hardware abstraction layer (HAL) and essential kernel services for embedded systems.
+
+## Features
+
+- **Device and Driver Model**: A flexible system for managing hardware devices and their corresponding drivers.
+- **Peripheral Support**: Standard interfaces for common peripherals:
+    - GPIO (General Purpose Input/Output)
+    - I2C (Inter-Integrated Circuit)
+    - I2S (Inter-IC Sound)
+    - SPI (Serial Peripheral Interface)
+    - UART (Universal Asynchronous Receiver-Transmitter)
+- **Concurrency Primitives**: Built-in support for multi-threaded environments, including:
+    - Threads and Dispatchers
+    - Mutexes and Recursive Mutexes
+    - Event Groups
+    - Timers
+- **Module System**: Support for loadable modules that can export symbols and provide runtime-extensible functionality.
+- **Device Tree Integration**: Utilizes a devicetree-like system for hardware configuration and initialization.
+- **Cross-Platform**: Designed to run on both embedded platforms (such as ESP32) and desktop environments (Linux) for simulation and testing.
