[PATCH 00/13] cpus: Constify @cpu in SysemuCPUOps::has_work() handler

["Philippe Mathieu-Daudé" <philmd@oss.qualcomm.com>]

- Patches 1-8 trivially add const qualifier for various
  cpu_is/has() getters
- Patch 9 adds const-qualified variants of cpu_env() and
  env_archcpu(). Not sure if this is a good idea so marked
  as RFC.
- Patches 10-12 complete the cpu_is/has() getters const
  conversion using the new env_archcpu_const() variant
- Patch 13 finally convert the SysemuCPUOps::has_work
  hook and all target implementations.

No functional change; purely const-correctness improvment
to enforce has_work() callees don't mutate CPUState.

Build-tested.

Based-on: <20260819145649.23439-1-philmd@oss.qualcomm.com>
  "Make halt-to-exec transition explicit and remove cpu_exec_halt"
