target/xtensa: Use env_cpu, env_archcpu 

Cleanup in the boilerplate that each target must define.
Replace xtensa_env_get_cpu with env_archcpu.  The combination
CPU(xtensa_env_get_cpu) should have used ENV_GET_CPU to begin;
use env_cpu now.

Move cpu_get_tb_cpu_state below the include of "exec/cpu-all.h"
so that the definition of env_cpu is available.
