Kevin O'Connor 99f96f2832 bltouch: Use pin_down mode for probing
The BLTouch is more accurate when probing in "pin_down" mode than
"touch_mode" (at least on some hardware).  Rework the code to use that
mode.

When probing in pin_down mode, the BLTouch can go into an error state
if a pin_up is not sent immediately after a touch signal.  Rework the
pin_up code to reduce the time it takes to transmit the command.
