extmod/modmachine: Provide common implementation of disable/enable_irq.
The ports esp32, mimxrt, rp2 and samd all shared exactly the same
implementation of machine.disable_irq() and machine.enable_irq(),
implemented in terms of MICROPY_{BEGIN,END}_ATOMIC_SECTION. This commit
factors these implementations into extmod/modmachine.c.
The cc3200, esp8266, nrf, renesas-ra and stm32 ports do not yet use this
common implementation.
