Implemented binary resistances and some more (#18933)

- Fixed possible exploit with tamed pets having template immunities
- Implemented binary resistances
- Corrected resistances calculations
- Pets properly inherit players spell penetration
- Fixed doubled block calculation for damaging melee spells
- Auras removing snare effects will only remove the snaring component
- Shapeshifting will properly remove movement impairing auras only and not crowd control (dragon's breath)
- Immunities are properly checked versus all schools appearing in spell, unit is immune only if immune to all schools
- Spells with melee and magic school mask should compare armor reduction with resistances and select smaller reduction
- Demonic Circle: Teleport no longer removes root effects
