  1. runqueue: allocate threads to >= 1 cores 

    Support multiple cores in the runqueue.
The current allocation for each core is stored in a new array.
Thus, any call to `get_next_for_core` is minimal effort.
The allocation is updated after each change in the runqueue.

  6. fixup! threads: PoC multicore support for rp2040 

    Only schedule a context switch if thread allocation (to a core) changed.

TODO:
Schedule the context switch on the core that is affected. In most cases,
this is the currently running cores, but not always (e.g. when on
another core a low priority thread is running that should be preempted).
