This will solve 2 issues on tool change.
1) when no home is done ("no_move" is set) tool change should never move X & Y because... I don't know where I am...only Z should be adjusted to avoid bed collision if other nozzle is lower than current.
Since no move no bed level matrix should be applied
2) When SWITCHING_NOZZLE is enabled and system is homed there are two movements to go to destination, but first can move Z to older position and then crash on the bed
* [2.0.x] Fix NO_MOTION_BEFORE_HOMING unwanted behaviour
NO_MOTION_BEFORE_HOMING should prevent XYZ movements only when homing is not done.
E axes should be allowed
* Update G0_G1.cpp
* Update G0_G1.cpp

When M405 is used it changes 'volumetric_multiplier[FILAMENT_SENSOR_EXTRUDER_NUM]' value. When M406 disables M405 it leaves the value unchanged.
This PR applies 'calculate_volumetric_multipliers' in M406 instead of resetting it to 1.0 because M200 may not be compatible with M405 hence I'm sure to restore anyway with correct value.
#7504 integration has missed this part.
When more than 1 servo is used with bltouch it's impossible to predefine default servo delay for it.
In my original fix I completely removed this part but maybe this is a better compromise
