Stefan Kalkowski 8e13b376b0 hw: improve cross-cpu synchronization
This commit addresses several multiprocessing issues in base-hw:

* it reworks cross-cpu maintainance work for TLB invalidation by
  introducing a generic Inter_processor_work and removes the so
  called Cpu_domain_update
* thereby it solves the cross-cpu thread destruction, when the
  corresponding thread is active on another cpu (fix #3043)
* it adds the missing TLB shootdown for x86 (fix #3042)
* on ARM it removes the TLB shootdown via IPIs, because this
  is not needed on the multiprocessing ARM platforms we support
* it enables the per-cpu initialization of the kernel's cpu
  objects, which means those object initialization is executed
  by the proper cpu
* it rollbacks prior decision to make multiprocessing an aspect,
  but puts back certain 'smp' mechanisms (like cross-cpu lock)
  into the generic code base for simplicity reasons
