Merge remote-tracking branch 'remotes/philmd/tags/abstract-arch-cpu-20220307' into staging

- Re-org accel/ and softmmu/ to have more target-agnostic objects.

- Use CPUArchState as an abstract type, defined by each target
  (CPUState is our interface with generic code, CPUArchState is
   our interface with target-specific code).
