Introduce endstop interrupts If ENDSTOP_INTERRUPTS_FEATURE is enabled this tries to set up interrupt routines for all used endstop pins. If this worked without errors, `endstops.update()` is called only if one of the endstops changed its state. The new interrupt routines do not really check the endstops and react upon them. All what they do, is to set a flag if it makes sense to call the endstop test we are used to. This can be used on: * ARM (DUE) based boards - all pins can raise interrupts, * RAMPS - all 6 endstop pins plus some other on EXT-2 can raise interrupts, * RAMPS based boards - as long the designers did not change the pins for the endstops or at least left enough, * all boards, if there are enough pins that can raise interrupts, and you are willing/able to swap with pins dedicated to other purpose.

* Without endstop interrupts the endstop pins must be polled continually in
* the stepper-ISR via endstops.update(), most of the time finding no change.
* With this feature endstops.update() is called only when we know that at
* least one endstop has changed state, saving valuable CPU cycles.
*
* This feature only works when all used endstop pins can generate either an
* 'external interrupt' or a 'pin change interrupt'.
*
* Test whether pins issue interrupts on your board by flashing 'pin_interrupt_test.ino'.
* (Located in Marlin/buildroot/share/pin_interrupt_test/pin_interrupt_test.ino)

* Patch for pins_arduino.h (...\Arduino\hardware\arduino\avr\variants\mega\pins_arduino.h)
*
* These macros for the Arduino MEGA do not include the two connected pins on Port J (D13, D14).
* So we extend them here because these are the normal pins for Y_MIN and Y_MAX on RAMPS.
* There are more PCI-enabled processor pins on Port J, but they are not connected to Arduino MEGA.

Introduce endstop interrupts If ENDSTOP_INTERRUPTS_FEATURE is enabled this tries to set up interrupt routines for all used endstop pins. If this worked without errors, `endstops.update()` is called only if one of the endstops changed its state. The new interrupt routines do not really check the endstops and react upon them. All what they do, is to set a flag if it makes sense to call the endstop test we are used to. This can be used on: * ARM (DUE) based boards - all pins can raise interrupts, * RAMPS - all 6 endstop pins plus some other on EXT-2 can raise interrupts, * RAMPS based boards - as long the designers did not change the pins for the endstops or at least left enough, * all boards, if there are enough pins that can raise interrupts, and you are willing/able to swap with pins dedicated to other purpose.
