sam4e8e: Add the SAM4e8e port

Browse Source 
This can be flashed to e.g. the duet wifi using bossac. It requires a
later version as is currently included in the klipper repo (1.8
vs. 1.2). Comms are currently via UART0 only, USB serial is still TBD

On AVR platforms, the highest achievable step rate is with just one
stepper stepping. On the STM32F103, Arduino Zero, and Due, the highest
step rate is with two simultaneous steppers stepping. On the PRU and
step rate is with two simultaneous steppers stepping. On the PRU, SAM4E8E and
LPC176x, the highest step rate is with three simultaneous steppers.
