New VA108xx Rust workspace structure + dependency updates

- The workspace is now a monorepo without submodules. The HAL, PAC and BSP
  are integrated directly
- Update all dependencies: embedded-hal v1 and RTIC v2

+//! Blinky examples using the PAC directly, the HAL, or the BSP
+//!
+//! Additional note on LEDs:
+//! Be not afraid: Pulling the GPIOs low makes the LEDs blink. See REB1
+//! schematic for more details.
