Numerically optimized versions of *EI shapers have been tuned
for specific ranges of damping ratios and will show poor stability
outside of these designated ranges.

Don't try to infer when the step generation scan window may change.
Instead, require the input_shaper and pressure_advance code call
motion_queuing.check_step_generation_scan_windows() any time a
scanning window may change.

Remove the toolhead note_step_generation_scan_time() code and
automatically detect the itersolve scan windows that are in use.

This reverts commit 6749985302.
A defect was found in the above commit (the input shaper code calls
note_step_generateion_scan_time() for many steppers, so the
input_shaper class can't be used as the index).

Input shaping can help to reduce printer vibrations due to resonances
and eliminate or reduce ghosting in prints.
