Re-implement Core2 and other improvements (#141)

- Create real drivers instead of wrapping M5Unified/M5GFX
- Display HAL improvements (better default base class behaviour)
- Fixed bug with LVGL statusbar service locking (would hang indefinitely waiting for mutex, causing WDT issues)
- Fixes for `Critical.h`
- Fixes and improvements for `Dispatcher` and `DispatcherThread`
