target-arm: Change cpu_arm_init() return type to ARMCPU

Make cpu_arm_init() return a QOM ARMCPU, so that we don't need to
obtain an ARMCPU through arm_env_get_cpu() in machine init code.
This requires to adjust the inclusion site of cpu-qom.h and in turn,
forward-looking, to homogenize its include order.

cpu_init() must still return a CPUARMState for backwards and
cross-target compatibility, so adjust the cpu_init macro.
