target-arm: Override do_interrupt for ARMv7-M profile
Enable ARMCPUInfo to specify a custom class_init functions. Introduce arm_v7m_class_init() and use it for "cortex-m3" model. Instead of forwarding from arm_cpu_do_interrupt() to do_interrupt_v7m(), override CPUClass::do_interrupt with arm_v7m_cpu_do_interrupt() in arm_v7m_class_init().
