[2.0] Fix M48 for delta printers/ABL compile issue (#8286)

* fix M48 for delta printers

fix M48 for delta printers. home printer if not already homed.

* remove ENABLED(DELTA)

remove ENABLED(DELTA) as it is not needed.

* Update M48.cpp

* abl needs queue.h

without queue.h abl will not compile since there is a script that runs at the end of it and we need to queue it up.
