py/scheduler: Allow a port to specify attrs for mp_keyboard_interrupt.
Functions like mp_keyboard_interrupt() may need to be called from an IRQ handler and may need to be in a special memory section, so provide a generic wrapping macro for a port to do this. The macro name is chosen to be MICROPY_WRAP_<function name in uppercase> so that (in the future with more wrappers) each function could potentially be handled separately.
