[PATCH v2 00/15] cpus: Constify @cpu in SysemuCPUOps::has_work() handler

Missing review: 2,12,14,15

Since v1:
  - use _Generic (rth)
  - no more RFC

- Patches 2-11 trivially add const qualifier for various
  cpu_is/has() getters
- Patch 12-14 add const-qualified variants of cpu_env(),
  env_cpu(), and env_archcpu() using _Generic() macros;
  consolidate the redundant env_cpu_const() alias and update
  linux-user to use the generic accessor
- Patch 15 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.
