cpu: Add CPUArchState pointer to CPUState
The target-specific ENV_GET_CPU() macros have allowed us to navigate from CPUArchState to CPUState. The reverse direction was not supported. Avoid introducing CPU_GET_ENV() macros by initializing an untyped pointer that is initialized in derived instance_init functions. The field may not be called "env" due to it being poisoned.
