Rewrite SpellHitResult

Rename SPELL_ATTR_EX3_CANT_MISS to SPELL_ATTR3_IGNORE_HIT_RESULT.
Rewrite SPELL_ATTR3_IGNORE_HIT_RESULT code parts.
You can no longer dodge or parry while casting or lost control.
Only reduce chance from spell to hit when having a debuff at SPELL_AURA_MOD_DEBUFF_RESISTANCE.
You can no longer resist spells casted on yourself.
Spells wich skipped all checks in ::cast will also skip checks in SpellHitResult (except immune ofc)
