[2.0.x] Implement NANODLP_Z_SYNC for 2.0.x

These changes may need to be warmed over.  I tried to fix things with
the least amount of disruption.   I just wanted to get the bugfix_v2.0.0
branch working for people again.

Remove pin count check for MIGHTYBOARD_REVE

[2.0.x] tool change bad behaviours

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
