servo: Asynchronous adjustments of servo position
This change follows the same approach as implemented for fan control.
The change removes the move queue flushing when changing servo position,
which does not appear to be necessary. This can be beneficial, for
example, for WS7040-based cooling on IDEX setups where the servo can
be used to control the air flow between the toolheads, with this change
eliminating micro-stutters of the toolhead on servo position adjustment.
