Add sanity check for MAXIMUM_STEPPER_RATE

[AndreySamokhin]

Description

It was observed that when the actual stepper motor rate (calculated from DEFAULT_AXIS_STEPS_PER_UNIT and DEFAULT_MAX_FEEDRATE) exceeds hardware limitations (i.e., MAXIMUM_STEPPER_RATE), unpredictable behavior occurs (#27496).

Several lines of code were added to SanityCheck.h to trigger a compile-time error in such cases.

Example

Use extreme values for DEFAULT_MAX_FEEDRATE to trigger a compile-time error.

  #define DEFAULT_MAX_FEEDRATE          { 300, 30000, 5, 25 }

error: static assertion failed: For the Y axis, the maximum stepper rate calculated from DEFAULT_AXIS_STEPS_PER_UNIT and DEFAULT_MAX_FEEDRATE exceeds 500000 (i.e., MAXIMUM_STEPPER_RATE).

Requirements

No specific hardware components are required.

Benefits

This change ensures a compile-time error occurs instead of the unpredictable behavior that might occur otherwise.

Configurations

This applies to all configurations where MAXIMUM_STEPPER_RATE is defined.

Build Test (LPC1769) (.../examples/Azteeg/X5GT) failed with error: static assertion failed: Slow down! DEFAULT_MAX_FEEDRATE[X] * DEFAULT_AXIS_STEPS_PER_UNIT[X] > MAXIMUM_STEPPER_RATE (15000). I do not understand why MAXIMUM_STEPPER_RATE is set to 15000, it should be 50000. I compiled it locally without errors.

I do not understand why MAXIMUM_STEPPER_RATE is set to 15000, it should be 50000. I compiled it locally without errors.

The currently failing test is ["Test LPC1769] Cohesion3D Remix DELTA | ABL Bilinear | EEPROM | Sensorless Homing/Probing | I Axis..."

example has "#define I_DRIVER_TYPE TB6560" so it gets set to the slowest driver

  #if HAS_DRIVER(TB6560)
    #define MAXIMUM_STEPPER_RATE 15000

This is set as part of the test https://github.com/MarlinFirmware/Marlin/blob/bugfix-2.1.x/buildroot/tests/LPC1769#L47

as is

        DEFAULT_AXIS_STEPS_PER_UNIT '{ 80, 80, 400, 500, 80 }' \
        DEFAULT_MAX_FEEDRATE '{ 300, 300, 5, 25, 300 }' \

X:  80*300 = 24000 Fail   
Y:  80*300 = 24000 Fail
Z:  400*5  = 2000  Pass
I:  500*25 = 12500 Pass
E:  80*300 = 24000 Fail

If you update the test file buildroot/tests/LPC1769 lines 48-49 with valid values, this test will pass

@ellensp, thank you for the clarification! Initially I mistakenly thought that considering all configurations from Configurations/config/examples/ would be enough. Now I see that all scripts from Marlin/buildroot/tests/ should also be taken into account.
