[Bots] Add Bot-specific Spell Settings. (#2553)

* [Bots] Add Bot-specific Spell Settings.

# Notes
- Allows players to set `priority`, `min_level`, `max_level`, `min_hp`, `max_hp`, and `is_enabled` settings per spell based on targeted bot.
- Lets players disable spells they don't want their bots casting or change the criteria they cast them at if they want.

* Update botspellsai.cpp

* Update 2022_11_19_bot_spell_settings.sql

* Typo.

* Update botspellsai.cpp

* Cleanup and add Reload Methods to Perl/Lua.
