Partial reimplementation of TactilityC GPIO (#469)

Browse Source 
* **New Features**
  * Added a GPIO hardware abstraction layer for reading pin levels from applications.
  * Applications can now query the number of available GPIO pins so they can adapt to different devices.
* **Chores**
  * Integrations updated so GPIO capabilities are discoverable and exported to running applications.
