Speed tweaks

Smoother motion by fixing calculating trapezoids and ISR stepping.

Fix rounding directions in calculate_trapezoid_for_block().
Fix off-by-ones errors in ac/deceleration steps in block_phase_isr.
Half-initialize ac/deceleration_time to smooth the speed change shock that happens between segments, which is critical as jerk/deviation adds to this.

The result is a smoother motion profile that follows the imposed acceleration limits with a well defined 0.5-1.5x error factor (or 2x if axis is starting from ~0). Errors are due to converting a real-valued motion profile into discrete numbers of steps.
Fixes are general and improve S_CURVE_ACCELERATION too (no endorsement implied).

Tested by looking at the generated step/dir impulses with a logic analyzer.

Enjoy the smoother motion or use more aggresive acceleration/jerk/deviation values for faster prints.

Also improves: #12491

Remove nominal_length, remove MINIMAL_STEP_RATE, add min_entry_speed_sqr, initial clean up of reverse_pass_kernel and forward_pass_kernel.

Removing MINIMAL_STEP_RATE allows for correct handling of moves with low acceleration, including fixing judder that's caused when the planner computes an entry speed based on minimum_planner_speed_sqr that's then promptly overriden by MINIMAL_STEP_RATE.

Added min_entry_speed_sqr to avoid a specific potential source of judder due to working with discrete steps rather continuous real-valued physics. The first step of any segment runs at initial_rate. If it is too low compared to acceleration_steps_per_s2 it will result in too much accumulated acceleration_time (see stepper.cpp) which will mean the following step will be at a much higher speed, and the speed change will significantly surpass the set acceleration_steps_per_s2 limit. Making sure we can match this limit is why we have minimum_planner_speed_sqr in the first place.

Optimal number of sqrts and trapezoid calculations.

Remove forward_pass(). Call forward_pass_kernel() from recalculate() instead.
Fix potential for large speed changes if planner falls behind.

- * Peltier Bed - Heating and Cooling
- *
- * A Peltier device transfers heat from one side to the other in proportion to the amount of
- * current flowing through the device and the direction of current flow. So the same device
- * can both heat and cool.
- *
- * When "cooling" in addition to rejecting the heat transferred from the hot side to the cold
- * side, the dissipated power (voltage * current) must also be rejected. Be sure to set up a
- * fan that can be powered in sync with the Peltier unit.
- *
- * This feature is only set up to run in bang-bang mode because Peltiers don't handle PWM
- * well without filter circuitry.
- *
- * Since existing 3D printers are made to handle relatively high current for the heated bed,
- * we can use the heated bed power pins to control the Peltier power using the same G-codes
- * as the heated bed (M140, M190, etc.).
- *
- * A second GPIO pin is required to control current direction.
- * Two configurations are possible: Relay and H-Bridge
- *
- * (At this time only relay is supported. H-bridge requires 4 MOS switches configured in H-Bridge.)
- *
- * Power is handled by the bang-bang control loop: 0 or 255.
- * Cooling applications are more common than heating, so the pin states are commonly:
- *   LOW  = Heating = Relay Energized
- *   HIGH = Cooling = Relay in "Normal" state

+ * Endstop Interrupts
+ *
+ * Without endstop interrupts the endstop pins must be polled continually in
+ * the temperature-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 an 'external 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)
