[7886] Drop use table petcreateinfo_spell

This is first commit in chain for remove oudated and not used pet functionality.

    * Use instead dropped table CreatureSpellData.dbc if creature_template.PetSpellDataId set (mostly hunter pets)
    * Use creature_template.spellN if not set creature_template.PetSpellDataId (mostly different summon creatures)
    * Fixed bug with not removing from action bar spell icon for not ranked unlearned spells.

    Note: summoned controllable creatures without PetSpellDataId must have expected spells in spellN feilds for creature_template.

[7887] Drop pet spell teaching code, including field in character_pet.
