94beeabd2e py/obj: Convert make_new into a mp_obj_type_t slot.
Instead of being an explicit field, it's now a slot like all the other
methods.

This is a marginal code size improvement because most types have a make_new
(100/138 on PYBV11), however it improves consistency in how types are
declared, removing the special case for make_new.

662b9761b3 all: Make all mp_obj_type_t defs use MP_DEFINE_CONST_OBJ_TYPE.
In preparation for upcoming rework of mp_obj_type_t layout.

c2e4759cfa mimxrt/modmachine: Implement machine.WDT() and machine.reset_cause().
The API follows that of rp2, stm32, esp32, and the docs.

    wdt=machine.WDT(0, timeout)

        Timeout is given in ms. The valid range is 500 to 128000 (128
        seconds) with 500 ms granularity. Values outside of that range will
        be silently aligned.

    wdt.feed()

        Resets the watchdog timer (feeding).

    wdt.timeout_ms(value)

        Sets a new timeout and feeds the watchdog.

        This is a new, preliminary method which is not yet documented.

    reset_cause = machine.reset_cause()

        Values returned:

        1  Power On reset
        3  Watchdog reset
        5  Software reset: state after calling machine.reset()

More elaborate API functions are supported by the MCU, like an interrupt
called a certain time after feeding.  But for port cosistency that is not
implemented.
