When MICROPY_PY_THREAD is enabled, ISR cannot be used for anything except mp_sched_schedule.

That's because a call to MP_STATE_THREAD (by nlr_push for example) calls pvTaskGetThreadLocalStoragePointer which is invalid in ISR context.

Perhaps Micropython should allocate state for ISR context as well?
