The target here is to update the screens of graphical and char base
displays as fast as possible, without draining the planner buffer too much.

For that measure the time it takes to draw and transfer one
(partial) screen to the display. Build a max. value from that.
Because ther can be large differences, depending on how much the display
updates are interrupted, the max value is decreased by one ms/s. This way
it can shrink again.
On the other side we keep track on how much time it takes to empty the
planner buffer.
Now we draw the next (partial) display update only then, when we do not
drain the planner buffer to much. We draw only when the time in the
buffer is two times larger than a update takes, or the buffer is empty anyway.

When we have begun to draw a screen we do not wait until the next 100ms
time slot comes. We draw the next partial screen as fast as possible, but
give the system a chance to refill the buffers a bit.

When we see, during drawing a screen, the screen contend has changed,
we stop the current draw and begin to draw the new content from the top.

`Z_MIN_ENDSTOP_INVERTING` must match `Z_MIN_PROBE_ENDSTOP_INVERTING`
when using `Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN`.
This is easy to overlook.

And reduce the function size to simplify

・Update forgotten Configuration_adv.h of Felix\DUAL and K8400\Dual-head

・Make descriptions the same as others

.. and give the hint to try lower values if possible.

Simply apply enabled settings instead of requiring users to edit
stepper_indirection.cpp

- Fix typos, verbiage
- Fix naming of `setup_endstop_interrupts`
- Some formatting, indentation, spacing

Configuration.h: back in sync, new features configured
Configuration_adv.h: back in sync, new features configured
README.md: text updated

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.

・Update forgotten K8400\Dual-head\Configuration.h
・Adjust spacing
