[11299] Handle aura durations in SpellAuraHolder

Browse source 
- Unit::CalculateSpellDuration split into two functions
    - CalculateSpellDuration taking into account combo points and caster-side spell mods
    - Unit::CalculateAuraDuration taking into account target-side spell mods
- Diminishing is now applied before duration reduction mods
- Implement saving per-effect periodic timers to DB (required for auras affected by haste)
