[8308] More generic code for new continent spell casting including fly form/mounts.

* Check new continent requirement by SPELL_ATTR_EX4_CAST_ONLY_IN_OUTLAND in
  SpellMgr::GetSpellAllowedInLocationError.
* Also in this function let ignore any area requirement in GM-mode (except client side checks ofc if use spellbook/item)
* For fly form/mount auras check only speciaal reqirement like special fly skill and ignore it for dead state.
* Drop explicit fly auras drop at zone update, now this part GetSpellAllowedInLocationError functionality.
* Allow in `spell_area` have data deepndent from ghost auras

This all allow implement apply spells 55173/55164 to player ghost wiht DB support in `spell_area`
