[PATCH 00/24] exec: Rework around CPUState user fields (part 2)

[Philippe Mathieu-Daudé]

Finish extracting TCG fields from CPUState:
- Extract tcg_cpu_exit() from cpu_exit()
- Introduce AccelOpsClass::exit_vcpu_thread()
- cpu_exit() calls exit_vcpu_thread=tcg_cpu_exit for TCG
- Forward declare TaskState and more uses of get_task_state()
- Introduce TCG AccelCPUState
- Move TCG specific fields from CPUState to AccelCPUState
- Restrict "exec/tlb-common.h" to TCG
- Restrict iommu_notifiers, icount to system emulation

Based-on: <20240428214915.10339-1-philmd@linaro.org>
