Rework library structure

Changed:

- Move most library components to new [`vorago-shared-periphs`](https://egit.irs.uni-stuttgart.de/rust/vorago-shared-periphs)
  which is mostly re-exported in this crate.
- Overhaul and simplification of several HAL APIs. The system configuration and IRQ router
  peripheral instance generally does not need to be passed to HAL API anymore.
- All HAL drivers are now type erased. The constructors will still expect and consume the PAC
  singleton component for resource management purposes, but are not cached anymore.
- Refactoring of GPIO library to be more inline with embassy GPIO API.

Added:

- I2C clock timeout feature support.
