Added an error code for laser mode when VARIABLE_SPINDLE is disabled.

- When trying to enable laser mode with $32=1 and VARIABLE_SPINDLE is
disabled, the error code shown was improperly stating it was a homing
failure. Added an new error code specifically for the laser mode being
disabled without VARIABLE_SPINDLE.

+Subject: Fixed $G report issue with M7 and M8 both enabled.
+
+[fix] When M7 and M8 are both enabled, $G report would show `M78`,
+rather than `M7 M8`. This only effects systems that enable M7 mist
+coolant in config.h. Not the default build.
