ENH: support spiral lift with timelapse gcode
The existing implementation did only read the new Z position from the injected timelapse_gcode and flagged the position as unsafe because of this.

This change reads X, Y and Z pos from the timelapgse_gcode and will keep the position state correct to enable safety checks required for using spiral Z hop.

Because of this, spiral Z hop can be used everyhwere now. The same pattern is also applied for layer_change/toolhead gcode injection.

The set_current_position_clear method is unused but will be kept in implementation for future scenarios.
