Ubl delta fixes and improvements (#6941)
* Change all direct changes of ubl.state.active to set_bed_leveling_enabled() which handles apply/unapply leveling to maintain current_position consistency. Fix invalidation of UBL mesh to invalid unreachable mesh points as well (delta corners). Fix UBL_DELTA unapply_leveling logic and when it gets applied, including fade_height changes. Add optional M114 D for detailed position information, disabled from compilation by default (M114_DETAIL). * UBL_DELTA raw and inline kinematics * UBL planner fall through fix * consistent variable names * Cleanup orphaned code and whitespace changes. Use _O2. * compile warnings cleanup * Remove redundant #ifdef condition
